This adds LDA to spark.ml, the Pipelines API. It follows the design doc in the JIRA: [https://issues.apache.org/jira/browse/SPARK-5565], with one major change: * I eliminated doc IDs. These are not necessary with DataFrames since the user can add an ID column as needed. Note: This will conflict with [https://github.com/apache/spark/pull/9484], but I'll try to merge [https://github.com/apache/spark/pull/9484] first and then rebase this PR. CC: hhbyyh feynmanliang If you have a chance to make a pass, that'd be really helpful--thanks!

This patch re-enables tests for the Docker JDBC data source. These tests were reverted in #4872 due to transitive dependency conflicts introduced by the `docker-client` library. This patch should avoid those problems by using a version of `docker-client` which shades its transitive dependencies and by performing some build-magic to work around problems with that shaded JAR. In addition, I significantly refactored the tests to simplify the setup and teardown code and to fix several Docker networking issues which caused problems when running in `boot2docker`. Closes #8101. Author: Josh Rosen <joshrosen@databricks.com> Author: Yijie Shen <henry.yijieshen@gmail.com> Closes #9503 from JoshRosen/docker-jdbc-tests.

Implementation of step capability for sliding window function in MLlib's RDD. Though one can use current sliding window with step 1 and then filter every Nth window, it will take more time and space (N*data.count times more than needed). For example, below are the results for various windows and steps on 10M data points: Window | Step | Time | Windows produced ------------ | ------------- | ---------- | ---------- 128 | 1 | 6.38 | 9999873 128 | 10 | 0.9 | 999988 128 | 100 | 0.41 | 99999 1024 | 1 | 44.67 | 9998977 1024 | 10 | 4.74 | 999898 1024 | 100 | 0.78 | 99990 ``` import org.apache.spark.mllib.rdd.RDDFunctions._ val rdd = sc.parallelize(1 to 10000000, 10) rdd.count val window = 1024 val step = 1 val t = System.nanoTime(); val windows = rdd.sliding(window, step); println(windows.count); println((System.nanoTime() - t) / 1e9) ``` Author: unknown <ulanov@ULANOV3.americas.hpqcorp.net> Author: Alexander Ulanov <nashb@yandex.ru> Author: Xiangrui Meng <meng@databricks.com> Closes #5855 from avulanov/SPARK-7316-sliding.

This patch adds the building blocks for codegening subexpr elimination and implements it end to end for UnsafeProjection. The building blocks can be used to do the same thing for other operators. It introduces some utilities to compute common sub expressions. Expressions can be added to this data structure. The expr and its children will be recursively matched against existing expressions (ones previously added) and grouped into common groups. This is built using the existing `semanticEquals`. It does not understand things like commutative or associative expressions. This can be done as future work. After building this data structure, the codegen process takes advantage of it by: 1. Generating a helper function in the generated class that computes the common subexpression. This is done for all common subexpressions that have at least two occurrences and the expression tree is sufficiently complex. 2. When generating the apply() function, if the helper function exists, call that instead of regenerating the expression tree. Repeated calls to the helper function shortcircuit the evaluation logic.

The way to create aggregate expressions is `AggregateExpression(aggregateFunction, mode, isDistinct)`. * Changing `val`s in `DeclarativeAggregate`s that touch children of this function to `lazy val`s (when we create aggregate expression in DataFrame API, children of an aggregate function can be unresolved).

This patch modifies Spark's SBT build so that it no longer uses `retrieveManaged` / `lib_managed` to store its dependencies. The motivations for this change are nicely described on the JIRA ticket ([SPARK-7841](https://issues.apache.org/jira/browse/SPARK-7841)); my personal interest in doing this stems from the fact that `lib_managed` has caused me some pain while debugging dependency issues in another PR of mine. Removing our use of `lib_managed` would be trivial except for one snag: the Datanucleus JARs, required by Spark SQL's Hive integration, cannot be included in assembly JARs due to problems with merging OSGI `plugin.xml` files. As a result, several places in the packaging and deployment pipeline assume that these Datanucleus JARs are copied to `lib_managed/jars`. In the interest of maintaining compatibility, I have chosen to retain the `lib_managed/jars` directory _only_ for these Datanucleus JARs and have added custom code to `SparkBuild.scala` to automatically copy those JARs to that folder as part of the `assembly` task. `dev/mima` also depended on `lib_managed` in a hacky way in order to set classpaths when generating MiMa excludes; I've updated this to obtain the classpaths directly from SBT instead. /cc dragos marmbrus pwendell srowen Author: Josh Rosen <joshrosen@databricks.com> Closes #9575 from JoshRosen/SPARK-7841.

This PR adds a new interface for user-defined aggregations, that can be used in `DataFrame` and `Dataset` operations to take all of the elements of a group and reduce them to a single value. For example, the following aggregator extracts an `int` from a specific class and adds them up: ```scala case class Data(i: Int) val customSummer = new Aggregator[Data, Int, Int] { def prepare(d: Data) = d.i def reduce(l: Int, r: Int) = l + r def present(r: Int) = r }.toColumn() val ds: Dataset[Data] = ... val aggregated = ds.select(customSummer) ``` By using helper functions, users can make a generic `Aggregator` that works on any input type: ```scala /** An `Aggregator` that adds up any numeric type returned by the given function. */ class SumOf[I, N : Numeric](f: I => N) extends Aggregator[I, N, N] with Serializable { val numeric = implicitly[Numeric[N]] override def zero: N = numeric.zero override def reduce(b: N, a: I): N = numeric.plus(b, f(a)) override def present(reduction: N): N = reduction } def sum[I, N : Numeric : Encoder](f: I => N): TypedColumn[I, N] = new SumOf(f).toColumn ``` These aggregators can then be used alongside other built-in SQL aggregations. ```scala val ds = Seq(("a", 10), ("a", 20), ("b", 1), ("b", 2), ("c", 1)).toDS() ds .groupBy(_._1) .agg( sum(_._2), // The aggregator defined above. expr("sum(_2)").as[Int], // A built-in dynatically typed aggregation. count("*")) // A built-in statically typed aggregation. .collect() res0: ("a", 30, 30, 2L), ("b", 3, 3, 2L), ("c", 1, 1, 1L) ``` The current implementation focuses on integrating this into the typed API, but currently only supports running aggregations that return a single long value as explained in `TypedAggregateExpression`. This will be improved in a followup PR. Author: Michael Armbrust <michael@databricks.com> Closes #9555 from marmbrus/dataset-useragg. -

Actually this was resolved by https://github.com/apache/spark/pull/8275. But I found the JIRA issue for this is not marked as resolved since the PR above was made for another issue but the PR above resolved both. I commented that this is resolved by the PR above; however, I opened this PR as I would like to just add a little bit of corrections. In the previous PR, I refactored the test by not reducing just collecting filters; however, this would not test properly `And` filter (which is not given to the tests). I unintentionally changed this from the original way (before being refactored). In this PR, I just followed the original way to collect filters by reducing. I would like to close this if this PR is inappropriate and somebody would like this deal with it in the separate PR related with this.

For now they are thin wrappers around the corresponding Hive UDAFs. One limitation with these in Hive 0.13.0 is they only support aggregating primitive types.
