[SPARK-14280][BUILD][WIP] Update change-version.sh and pom.xml to add Scala 2.12 profiles and enable 2.12 compilation …build; fix some things that will be warnings or errors in 2.12; restore Scala 2.12 profile infrastructure ## What changes were proposed in this pull request? This change adds back the infrastructure for a Scala 2.12 build, but does not enable it in the release or Python test scripts. In order to make that meaningful, it also resolves compile errors that the code hits in 2.12 only, in a way that still works with 2.11. It also updates dependencies to the earliest minor release of dependencies whose current version does not yet support Scala 2.12. This is in a sense covered by other JIRAs under the main umbrella, but implemented here. The versions below still work with 2.11, and are the _latest_ maintenance release in the _earliest_ viable minor release. - Scalatest 2.x -> 3.0.3 - Chill 0.8.0 -> 0.8.4 - Clapper 1.0.x -> 1.1.2 - json4s 3.2.x -> 3.4.2 - Jackson 2.6.x -> 2.7.9 (required by json4s) This change does _not_ fully enable a Scala 2.12 build: - It will also require dropping support for Kafka before 0.10. Easy enough, just didn't do it yet here - It will require recreating `SparkILoop` and `Main` for REPL 2.12, which is SPARK-14650. Possible to do here too. What it does do is make changes that resolve much of the remaining gap without affecting the current 2.11 build. ## How was this patch tested? Existing tests and build. Manually tested with `./dev/change-scala-version.sh 2.12` to verify it compiles, modulo the exceptions above. Author: Sean Owen <sowen@cloudera.com> Closes #18645 from srowen/SPARK-14280.

## What changes were proposed in this pull request? When use Vector.compressed to change a Vector to SparseVector, the performance is very low comparing with Vector.toSparse. This is because you have to scan the value three times using Vector.compressed, but you just need two times when use Vector.toSparse. When the length of the vector is large, there is significant performance difference between this two method. ## How was this patch tested?

This version fixes a few issues in the import order checker; it provides better error messages, and detects more improper ordering (thus the need to change a lot of files in this patch). The main fix is that it correctly complains about the order of packages vs. classes. As part of the above, I moved some "SparkSession" import in ML examples inside the "$example on$" blocks; that didn't seem consistent across different source files to start with, and avoids having to add more on/off blocks around specific imports. The new scalastyle also seems to have a better header detector, so a few license headers had to be updated to match the expected indentation.

## What changes were proposed in this pull request? This patch adds a `compressed` method to ML `Matrix` class, which returns the minimal storage representation of the matrix - either sparse or dense. Because the space occupied by a sparse matrix is dependent upon its layout (i.e. column major or row major), this method must consider both cases. It may also be useful to force the layout to be column or row major beforehand, so an overload is added which takes in a `columnMajor: Boolean` parameter. The compressed implementation relies upon two new abstract methods `toDense(columnMajor: Boolean)` and `toSparse(columnMajor: Boolean)`, similar to the compressed method implemented in the `Vector` class. These methods also allow the layout of the resulting matrix to be specified via the `columnMajor` parameter. More detail on the new methods is given below. ## How was this patch tested? Added many new unit tests ## New methods (summary, not exhaustive list) **Matrix trait** - `private[ml] def toDenseMatrix(columnMajor: Boolean): DenseMatrix` (abstract) - converts the matrix (either sparse or dense) to dense format - `private[ml] def toSparseMatrix(columnMajor: Boolean): SparseMatrix` (abstract) - converts the matrix (either sparse or dense) to sparse format - `def toDense: DenseMatrix = toDense(true)` - converts the matrix (either sparse or dense) to dense format in column major layout - `def toSparse: SparseMatrix = toSparse(true)` - converts the matrix (either sparse or dense) to sparse format in column major layout - `def compressed: Matrix` - finds the minimum space representation of this matrix, considering both column and row major layouts, and converts it - `def compressed(columnMajor: Boolean): Matrix` - finds the minimum space representation of this matrix considering only column OR row major, and converts it **DenseMatrix class** - `private[ml] def toDenseMatrix(columnMajor: Boolean): DenseMatrix` - converts the dense matrix to a dense matrix, optionally changing the layout (data is NOT duplicated if the layouts are the same) - `private[ml] def toSparseMatrix(columnMajor: Boolean): SparseMatrix` - converts the dense matrix to sparse matrix, using the specified layout **SparseMatrix class** - `private[ml] def toDenseMatrix(columnMajor: Boolean): DenseMatrix` - converts the sparse matrix to a dense matrix, using the specified layout - `private[ml] def toSparseMatrix(columnMajors: Boolean): SparseMatrix` - converts the sparse matrix to sparse matrix. If the sparse matrix contains any explicit zeros, they are removed. If the layout requested does not match the current layout, data is copied to a new representation. If the layouts match and no explicit zeros exist, the current matrix is returned. Author: sethah <seth.hendrickson16@gmail.com> Closes #15628 from sethah/matrix_compress.

## What changes were proposed in this pull request? Currently, single line comment does not mark down backticks to `<code>..</code>` but prints as they are (`` `..` ``). For example, the line below: ```scala /** Return an RDD with the pairs from `this` whose keys are not in `other`. */ ``` So, we could work around this as below: ```scala /** * Return an RDD with the pairs from `this` whose keys are not in `other`. */ ``` - javadoc - **Before**  - **After**  - scaladoc (this one looks fine either way) - **Before**  - **After**  I suspect this is related with SPARK-16153 and genjavadoc issue in ` typesafehub/genjavadoc#85`. ## How was this patch tested?

[SPARK-3359][BUILD][DOCS] More changes to resolve javadoc 8 errors that will help unidoc/genjavadoc compatibility ## What changes were proposed in this pull request? This PR only tries to fix things that looks pretty straightforward and were fixed in other previous PRs before. This PR roughly fixes several things as below: - Fix unrecognisable class and method links in javadoc by changing it from `[[..]]` to `` `...` `` ``` [error] .../spark/sql/core/target/java/org/apache/spark/sql/streaming/DataStreamReader.java:226: error: reference not found [error] * Loads text files and returns a {link DataFrame} whose schema starts with a string column named ``` - Fix an exception annotation and remove code backticks in `throws` annotation Currently, sbt unidoc with Java 8 complains as below: ``` [error] .../java/org/apache/spark/sql/streaming/StreamingQuery.java:72: error: unexpected text [error] * throws StreamingQueryException, if <code>this</code> query has terminated with an exception. ``` `throws` should specify the correct class name from `StreamingQueryException,` to `StreamingQueryException` without backticks. (see [JDK-8007644](https://bugs.openjdk.java.net/browse/JDK-8007644)). - Fix `[[http..]]` to `<a href="http..."></a>`. ```diff - * [[https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https Oracle - * blog page]]. + * <a href="https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https"> + * Oracle blog page</a>. ``` `[[http...]]` link markdown in scaladoc is unrecognisable in javadoc. - It seems class can't have `return` annotation. So, two cases of this were removed. ``` [error] .../java/org/apache/spark/mllib/regression/IsotonicRegression.java:27: error: invalid use of return [error] * return New instance of IsotonicRegression. ``` - Fix < to `<` and > to `>` according to HTML rules. - Fix `</p>` complaint - Exclude unrecognisable in javadoc, `constructor`, `todo` and `groupname`. ## How was this patch tested?

## What changes were proposed in this pull request? 1. Make a pluggable solver interface for `WeightedLeastSquares` 2. Add a `QuasiNewton` solver to handle elastic net regularization for `WeightedLeastSquares` 3. Add method `BLAS.dspmv` used by QN solver 4. Add mechanism for WLS to handle singular covariance matrices by falling back to QN solver when Cholesky fails. ## How was this patch tested? Unit tests - see below. ## Design choices **Pluggable Normal Solver** Before, the `WeightedLeastSquares` package always used the Cholesky decomposition solver to compute the solution to the normal equations. Now, we specify the solver as a constructor argument to the `WeightedLeastSquares`. We introduce a new trait: ````scala private[ml] sealed trait NormalEquationSolver { def solve( bBar: Double, bbBar: Double, abBar: DenseVector, aaBar: DenseVector, aBar: DenseVector): NormalEquationSolution } ```` We extend this trait for different variants of normal equation solvers. In the future, we can easily add others (like QR) using this interface. **Always train in the standardized space** The normal solver did not previously standardize the data, but this patch introduces a change such that we always solve the normal equations in the standardized space. We convert back to the original space in the same way that is done for distributed L-BFGS/OWL-QN. We add test cases for zero variance features/labels. **Use L-BFGS locally to solve normal equations for singular matrix** When linear regression with the normal solver is called for a singular matrix, we initially try to solve with Cholesky. We use the output of `lapack.dppsv` to determine if the matrix is singular. If it is, we fall back to using L-BFGS locally to solve the normal equations. We add test cases for this as well. ## Test cases I found it helpful to enumerate some of the test cases and hopefully it makes review easier. **WeightedLeastSquares** 1. Constant columns - Cholesky solver fails with no regularization, Auto solver falls back to QN, and QN trains successfully. 2. Collinear features - Cholesky solver fails with no regularization, Auto solver falls back to QN, and QN trains successfully. 3. Label is constant zero - no training is performed regardless of intercept. Coefficients are zero and intercept is zero. 4. Label is constant - if fitIntercept, then no training is performed and intercept equals label mean. If not fitIntercept, then we train and return an answer that matches R's lm package. 5. Test with L1 - go through various combinations of L1/L2, standardization, fitIntercept and verify that output matches glmnet. 6. Initial intercept - verify that setting the initial intercept to label mean is correct by training model with strong L1 regularization so that all coefficients are zero and intercept converges to label mean. 7. Test diagInvAtWA - since we are standardizing features now during training, we should test that the inverse is computed to match R. **LinearRegression** 1. For all existing L1 test cases, test the "normal" solver too. 2. Check that using the normal solver now handles singular matrices. 3. Check that using the normal solver with L1 produces an objective history in the model summary, but does not produce the inverse of AtA. **BLAS** 1. Test new method `dspmv`. ## Performance Testing This patch will speed up linear regression with L1/elasticnet penalties when the feature size is < 4096. I have not conducted performance tests at scale, only observed by testing locally that there is a speed improvement. We should decide if this PR needs to be blocked before performance testing is conducted. Author: sethah <seth.hendrickson16@gmail.com> Closes #15394 from sethah/SPARK-17748.

## What changes were proposed in this pull request? * changes the implementation of gemv with transposed SparseMatrix and SparseVector both in mllib-local and mllib (identical) * adds a test that was failing before this change, but succeeds with these changes. The problem in the previous implementation was that it only increments `i`, that is enumerating the columns of a row in the SparseMatrix, when the row-index of the vector matches the column-index of the SparseMatrix. In cases where a particular row of the SparseMatrix has non-zero values at column-indices lower than corresponding non-zero row-indices of the SparseVector, the non-zero values of the SparseVector are enumerated without ever matching the column-index at index `i` and the remaining column-indices i+1,...,indEnd-1 are never attempted. The test cases in this PR illustrate this issue. ## How was this patch tested? I have run the specific `gemv` tests in both mllib-local and mllib. I am currently still running `./dev/run-tests`. ## ___ As per instructions, I hereby state that this is my original work and that I license the work to the project (Apache Spark) under the project's open source license.

## What changes were proposed in this pull request? We're using `asML` to convert the mllib vector/matrix to ml vector/matrix now. Using `as` is more correct given that this conversion actually shares the same underline data structure. As a result, in this PR, `toBreeze` will be changed to `asBreeze`. This is a private API, as a result, it will not affect any user's application. ## How was this patch tested? unit tests Author: DB Tsai <dbt@netflix.com> Closes #13198 from dbtsai/minor.

## What changes were proposed in this pull request? (See https://github.com/apache/spark/pull/12416 where most of this was already reviewed and committed; this is just the module structure and move part. This change does not move the annotations into test scope, which was the apparently problem last time.) Rename `spark-test-tags` -> `spark-tags`; move common annotations like `Since` to `spark-tags` ## How was this patch tested? Jenkins tests. Author: Sean Owen <sowen@cloudera.com> Closes #13074 from srowen/SPARK-15290.

## What changes were proposed in this pull request? This PR moves Vector.toJson/fromJson to ml.linalg.VectorEncoder under mllib/ to keep mllib-local's dependency minimal. The json encoding is used by Params. So we still need this feature in SPARK-14615, where we will switch to ml.linalg in spark.ml APIs. ## How was this patch tested? Copied existing unit tests over. cc; dbtsai Author: Xiangrui Meng <meng@databricks.com> Closes #12802 from mengxr/SPARK-14653.

## What changes were proposed in this pull request? Before, spark.ml GaussianMixtureModel used the spark.mllib MultivariateGaussian in its public API. This was added after 1.6, so we can modify this API without breaking APIs. This PR copies MultivariateGaussian to mllib-local in spark.ml, with a few changes: * Renamed fields to match numpy, scipy: mu => mean, sigma => cov This PR then uses the spark.ml MultivariateGaussian in the spark.ml GaussianMixtureModel, which involves: * Modifying the constructor * Adding a computeProbabilities method Also: * Added EPSILON to mllib-local for use in MultivariateGaussian ## How was this patch tested? Existing unit tests Author: Joseph K. Bradley <joseph@databricks.com> Closes #12593 from jkbradley/sparkml-gmm-fix.

## What changes were proposed in this pull request? Implement some `hashCode` and `equals` together in order to enable the scalastyle. This is a first batch, I will continue to implement them but I wanted to know your thoughts. Author: Joan <joan@goyeau.com> Closes #12157 from joan38/SPARK-6429-HashCode-Equals.

## What changes were proposed in this pull request? This task will copy the Vector and Matrix classes from mllib to ml package in mllib-local jar. The UDTs and `since` annotation in ml vector and matrix will be removed from now. UDTs will be achieved by #SPARK-14487, and `since` will be replaced by /* since 1.2.0 */ The BLAS implementation will be copied, and some of the test utilities will be copies as well. Summary of changes: 1. In mllib-local/src/main/scala/org/apache/spark/**ml**/linalg/BLAS.scala - Copied from mllib/src/main/scala/org/apache/spark/**mllib**/linalg/BLAS.scala - logDebug("gemm: alpha is equal to 0 and beta is equal to 1. Returning C.") is removed in ml version. 2. In mllib-local/src/main/scala/org/apache/spark/**ml**/linalg/Matrices.scala - Copied from mllib/src/main/scala/org/apache/spark/**mllib**/linalg/Matrices.scala - `Since` was removed, and we'll use standard `/* Since /*` Java doc. Will be in another PR. - `UDT` related code was removed, and will use `SPARK-13944` https://github.com/apache/spark/pull/12259 to replace the annotation. 3. In mllib-local/src/main/scala/org/apache/spark/**ml**/linalg/Vectors.scala - Copied from mllib/src/main/scala/org/apache/spark/**mllib**/linalg/Vectors.scala - `Since` was removed. - `UDT` related code was removed. - In `def parseNumeric`, it was throwing `throw new SparkException(s"Cannot parse $other.")`, and now it's throwing `throw new IllegalArgumentException(s"Cannot parse $other.")` 4. In mllib/src/main/scala/org/apache/spark/**mllib**/linalg/Vectors.scala - For consistency with ML version of vector, `def parseNumeric` is now throwing `throw new IllegalArgumentException(s"Cannot parse $other.")` 5. mllib/src/main/scala/org/apache/spark/**mllib**/util/NumericParser.scala is moved to mllib-local/src/main/scala/org/apache/spark/**ml**/util/NumericParser.scala - All the `throw new SparkException` were replaced by `throw new IllegalArgumentException` ## How was this patch tested? unit tests Author: DB Tsai <dbt@netflix.com> Closes #12317 from dbtsai/dbtsai-ml-vector.
