* [SPARK-16535][BUILD] In pom.xml, remove groupId which is redundant ↵Xin Ren2016-07-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | definition and inherited from the parent https://issues.apache.org/jira/browse/SPARK-16535 ## What changes were proposed in this pull request? When I scan through the pom.xml of sub projects, I found this warning as below and attached screenshot ``` Definition of groupId is redundant, because it's inherited from the parent ``` ![screen shot 2016-07-13 at 3 13 11 pm](https://cloud.githubusercontent.com/assets/3925641/16823121/744f893e-4916-11e6-8a52-042f83b9db4e.png) I've tried to remove some of the lines with groupId definition, and the build on my local machine is still ok. ``` <groupId>org.apache.spark</groupId> ``` As I just find now `<maven.version>3.3.9</maven.version>` is being used in Spark 2.x, and Maven-3 supports versionless parent elements: Maven 3 will remove the need to specify the parent version in sub modules. THIS is great (in Maven 3.1). ref: http://stackoverflow.com/questions/3157240/maven-3-worth-it/3166762#3166762 ## How was this patch tested? I've tested by re-building the project, and build succeeded. Author: Xin Ren <iamshrek@126.com> Closes #14189 from keypointt/SPARK-16535.
* [SPARK-3359][DOCS] More changes to resolve javadoc 8 errors that will help ↵Sean Owen2016-07-161-1/+1
| | | | | | | | | | | | | | | | unidoc/genjavadoc compatibility ## What changes were proposed in this pull request? These are yet more changes that resolve problems with unidoc/genjavadoc and Java 8. It does not fully resolve the problem, but gets rid of as many errors as we can from this end. ## How was this patch tested? Jenkins build of docs Author: Sean Owen <sowen@cloudera.com> Closes #14221 from srowen/SPARK-3359.3.
* [SPARK-16477] Bump master version to 2.1.0-SNAPSHOTReynold Xin2016-07-111-1/+1
| | | | | | | | | | | | ## What changes were proposed in this pull request? After SPARK-16476 (committed earlier today as #14128), we can finally bump the version number. ## How was this patch tested? N/A Author: Reynold Xin <rxin@databricks.com> Closes #14130 from rxin/SPARK-16477.

* [SPARK-15413][ML][MLLIB] Change `toBreeze` to `asBreeze` in Vector and MatrixDB Tsai2016-05-277-28/+28
| | | | | | | | | | | | | | ## 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.
* [SPARK-15411][ML] Add @since to ml.stat.MultivariateOnlineSummarizer.scalaDB Tsai2016-05-191-3/+8
| | | | | | | | | | | | | | ## What changes were proposed in this pull request? Add since to ml.stat.MultivariateOnlineSummarizer.scala ## How was this patch tested? unit tests Author: DB Tsai <dbt@netflix.com> Closes #13197 from dbtsai/cleanup.
* [SPARK-14613][ML] Add @Since into the matrix and vector classes in ↵Pravin Gadakh2016-05-192-14/+94
| | | | | | | | | | | | | | | | spark-mllib-local ## What changes were proposed in this pull request? This PR add `Since` annotations in `Vectors.scala` and `Matrices.scala` of spark-mllib-local. ## How was this patch tested? Scala Style Checks. Author: Pravin Gadakh <prgadakh@in.ibm.com> Closes #13191 from pravingadakh/SPARK-14613.
* [SPARK-15290][BUILD] Move annotations, like @Since / @DeveloperApi, into ↵Sean Owen2016-05-171-0/+4
| | | | | | | | | | | | | | | | | | spark-tags ## 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.
* [SPARK-14653][ML] Remove json4s from mllib-localXiangrui Meng2016-04-303-62/+0
| | | | | | | | | | | | | | | | ## 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.

| | | | | | | | | | | | | | | | spark-mllib-local ## What changes were proposed in this pull request? This PR adds `since` tag into the matrix and vector classes in spark-mllib-local. ## How was this patch tested? Scala-style checks passed.

* [SPARK-14732][ML] spark.ml GaussianMixture should use MultivariateGaussian ↵Joseph K. Bradley2016-04-264-0/+274
| | | | | | | | | | | | | | | | | | | | | | | | | | in mllib-local ## 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.
* [SPARK-6429] Implement hashCode and equals togetherJoan2016-04-222-0/+6
| | | | | | | | | | | ## 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.
* [SPARK-14549][ML] Copy the Vector and Matrix classes from mllib to ml in ↵DB Tsai2016-04-1513-31/+4337
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mllib-local ## 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.

* [SPARK-14462][ML][MLLIB] Add the mllib-local build to maven pomDB Tsai2016-04-113-0/+138
| | | | | | | | | | | | | | | | | | | | ## 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. ## How was this patch tested? Unit tests mengxr tedyu holdenk Author: DB Tsai <dbt@netflix.com> Closes #12298 from dbtsai/dbtsai-mllib-local-build-fix.

## 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 test scope will still depend on spark-core and spark-core-test in order to use the common utilities, but the runtime will avoid any platform dependency. Couple platform independent classes will be moved to this package to demonstrate how this work. ## How was this patch tested? Unit tests Author: DB Tsai <dbt@netflix.com> Closes #12241 from dbtsai/dbtsai-mllib-local-build.
