      [SPARK-17807][CORE] split test-tags into test-JAR · afd9bc1d
      Ryan Williams authored
      Remove spark-tag's compile-scope dependency (and, indirectly, spark-core's compile-scope transitive-dependency) on scalatest by splitting test-oriented tags into spark-tags' test JAR.
      
      Alternative to #16303.

      [SPARK-14653][ML] Remove json4s from mllib-local · 0847fe4e
      Xiangrui Meng authored
      ## 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.

      [SPARK-14549][ML] Copy the Vector and Matrix classes from mllib to ml in mllib-local · 96534aa4
      DB Tsai authored
      ## 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`

      [SPARK-14462][ML][MLLIB] Add the mllib-local build to maven pom · efaf7d18
      DB Tsai authored
      ## What changes were proposed in this pull request?
      
      In order to separate the linear algebra, and vector matrix classes into a standalone jar, we need to setup the build first. This PR will create a new jar called mllib-local with minimal dependencies.
      
      The previous PR was failing the build because of `spark-core:test` dependency, and that was reverted. In this PR, `FunSuite` with `// scalastyle:ignore funsuite` in mllib-local test was used, similar to sketch.
      
      Thanks.

      [SPARK-6363][BUILD] Make Scala 2.11 the default Scala version · 289373b2
      Josh Rosen authored
      This patch changes Spark's build to make Scala 2.11 the default Scala version. To be clear, this does not mean that Spark will stop supporting Scala 2.10: users will still be able to compile Spark for Scala 2.10 by following the instructions on the "Building Spark" page; however, it does mean that Scala 2.11 will be the default Scala version used by our CI builds (including pull request builds).
      
      The Scala 2.11 compiler is faster than 2.10, so I think we'll be able to look forward to a slight speedup in our CI builds (it looks like it's about 2X faster for the Maven compile-only builds, for instance).
      
      After this patch is merged, I'll update Jenkins to add new compile-only jobs to ensure that Scala 2.10 compilation doesn't break.

      [SPARK-5466] Add explicit guava dependencies where needed. · f9e56945
      Marcelo Vanzin authored
      One side-effect of shading guava is that it disappears as a transitive
      dependency. For Hadoop 2.x, this was masked by the fact that Hadoop
      itself depends on guava. But certain versions of Hadoop 1.x also
      shade guava, leaving either no guava or some random version pulled
      by another dependency on the classpath.
      
      So be explicit about the dependency in modules that use guava directly,
      which is the right thing to do anyway.

      This PR:
      
      - Reenables `surefire`, and copies config from `scalatest` (which is itself an old fork of `surefire`, so similar)
      - Tells `surefire` to test only Java tests
      - Enables `surefire` and `scalatest` for all children, and in turn eliminates some duplication.
      
      For me this causes the Scala and Java tests to be run once each, it seems, as desired. It doesn't affect the SBT build but works for Maven. I still need to verify that all of the Scala tests and Java tests are being run.

      Cheng Lian authored
      JIRA issue: [SPARK-2410](https://issues.apache.org/jira/browse/SPARK-2410)
      
      Another try for #1399 & #1600. Those two PR breaks Jenkins builds because we made a separate profile `hive-thriftserver` in sub-project `assembly`, but the `hive-thriftserver` module is defined outside the `hive-thriftserver` profile. Thus every time a pull request that doesn't touch SQL code will also execute test suites defined in `hive-thriftserver`, but tests fail because related .class files are not included in the assembly jar.
      
      In the most recent commit, module `hive-thriftserver` is moved into its own profile to fix this problem. All previous commits are squashed for clarity.

      TODO
      
      - [x] Use `spark-submit` to launch the server, the CLI and beeline
      - [x] Migration guideline draft for Shark users
      
      ----
      
      Hit by a bug in `SparkSubmitArguments` while working on this PR: all application options that are recognized by `SparkSubmitArguments` are stolen as `SparkSubmit` options. For example:
      
      ```bash
      $ spark-submit --class org.apache.hive.beeline.BeeLine spark-internal --help
      ```
      
      This actually shows usage information of `SparkSubmit` rather than `BeeLine`.
      
      ~~Fixed this bug here since the `spark-internal` related stuff also touches `SparkSubmitArguments` and I'd like to avoid conflict.~~
      
      **UPDATE** The bug mentioned above is now tracked by [SPARK-2678](https://issues.apache.org/jira/browse/SPARK-2678). Decided to revert changes to this bug since it involves more subtle considerations and worth a separate PR.

      SPARK-1387. Update build plugins, avoid plugin version warning, centralize versions · 856c50f5
      Sean Owen authored
      Another handful of small build changes to organize and standardize a bit, and avoid warnings:
      
      - Update Maven plugin versions for good measure
      - Since plugins need maven 3.0.4 already, require it explicitly (<3.0.4 had some bugs anyway)
      - Use variables to define versions across dependencies where they should move in lock step
      - ... and make this consistent between Maven/SBT
      
      OK, I also updated the JIRA URL while I was at it here.

      SPARK-1251 Support for optimizing and executing structured queries · 9aadcffa
      Michael Armbrust authored
      This pull request adds support to Spark for working with structured data using a simple SQL dialect, HiveQL and a Scala Query DSL.
      
      *This is being contributed as a new __alpha component__ to Spark and does not modify Spark core or other components.*
      
      The code is broken into three primary components:
       - Catalyst (sql/catalyst) - An implementation-agnostic framework for manipulating trees of relational operators and expressions.
       - Execution (sql/core) - A query planner / execution engine for translating Catalyst’s logical query plans into Spark RDDs.  This component also includes a new public interface, SqlContext, that allows users to execute SQL or structured scala queries against existing RDDs and Parquet files.
       - Hive Metastore Support (sql/hive) - An extension of SqlContext called HiveContext that allows users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes.  There are also wrappers that allows users to run queries that include Hive UDFs, UDAFs, and UDTFs.
      
      A more complete design of this new component can be found in [the associated JIRA](https://spark-project.atlassian.net/browse/SPARK-1251).
      
      [An updated version of the Spark documentation, including API Docs for all three sub-components,](http://people.apache.org/~pwendell/catalyst-docs/sql-programming-guide.html) is also available for review.
      
      With this PR comes support for inferring the schema of existing RDDs that contain case classes.  Using this information, developers can now express structured queries that are automatically compiled into RDD operations.
      
      ```scala
      // Define the schema using a case class.
      case class Person(name: String, age: Int)
      val people: RDD[Person] =
        sc.textFile("people.txt").map(_.split(",")).map(p => Person(p(0), p(1).toInt))
      
      // The following is the same as 'SELECT name FROM people WHERE age >= 10 && age <= 19'
      val teenagers = people.where('age >= 10).where('age <= 19).select('name).toRdd
      ```
      
      RDDs can also be registered as Tables, allowing SQL queries to be written over them.
      ```scala
      people.registerAsTable("people")
      val teenagers = sql("SELECT name FROM people WHERE age >= 10 && age <= 19")
      ```
      
      The results of queries are themselves RDDs and support standard RDD operations:
      ```scala
      teenagers.map(t => "Name: " + t(0)).collect().foreach(println)
      ```
      
      Finally, with the optional Hive support, users can read and write data located in existing Apache Hive deployments using HiveQL.
      ```scala
      sql("CREATE TABLE IF NOT EXISTS src (key INT, value STRING)")
      sql("LOAD DATA LOCAL INPATH 'src/main/resources/kv1.txt' INTO TABLE src")
      
      // Queries are expressed in HiveQL
      sql("SELECT key, value FROM src").collect().foreach(println)
      ```
      
      ## Relationship to Shark
      
      Unlike Shark, Spark SQL does not act as a drop in replacement for Hive or the HiveServer. Instead this new feature is intended to make it easier for Spark developers to run queries over structured data, using either SQL or the query DSL. After this sub-project graduates from Alpha status it will likely become a new optimizer/backend for the Shark project.

      SPARK-1121: Include avro for yarn-alpha builds · c3f5e075
      Patrick Wendell authored
      This lets us explicitly include Avro based on a profile for 0.23.X
      builds. It makes me sad how convoluted it is to express this logic
      in Maven. @tgraves and @sryza curious if this works for you.
      
      I'm also considering just reverting to how it was before. The only
      real problem was that Spark advertised a dependency on Avro
      even though it only really depends transitively on Avro through
      other deps.
