* Fixing the type of the sentiment happiness valueYury Liavitski2016-03-071-2/+2
| | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Added the conversion to int for the 'happiness value' read from the file. Otherwise, later on line 75 the multiplication will multiply a string by a number, yielding values like "-2-2" instead of -4. ## How was this patch tested? Tested manually. Author: Yury Liavitski <seconds.before@gmail.com> Author: Yury Liavitski <yury.liavitski@il111.ice.local> Closes #11540 from heliocentrist/fix-sentiment-value-type.

* [SPARK-13013][DOCS] Replace example code in mllib-clustering.md using ↵Xin Ren2016-03-035-3/+186
| | | | | | | | | | | | | | | | | | | | | include_example Replace example code in mllib-clustering.md using include_example https://issues.apache.org/jira/browse/SPARK-13013 The example code in the user guide is embedded in the markdown and hence it is not easy to test. It would be nice to automatically test them. This JIRA is to discuss options to automate example code testing and see what we can do in Spark 1.6. Goal is to move actual example code to spark/examples and test compilation in Jenkins builds. Then in the markdown, we can reference part of the code to show in the user guide. This requires adding a Jekyll tag that is similar to https://github.com/jekyll/jekyll/blob/master/lib/jekyll/tags/include.rb, e.g., called include_example. `{% include_example scala/org/apache/spark/examples/mllib/KMeansExample.scala %}` Jekyll will find `examples/src/main/scala/org/apache/spark/examples/mllib/KMeansExample.scala` and pick code blocks marked "example" and replace code block in `{% highlight %}` in the markdown. See more sub-tasks in parent ticket: https://issues.apache.org/jira/browse/SPARK-11337 Author: Xin Ren <iamshrek@126.com> Closes #11116 from keypointt/SPARK-13013.
* [SPARK-13583][CORE][STREAMING] Remove unused imports and add checkstyle ruleDongjoon Hyun2016-03-0323-31/+3
| | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? After SPARK-6990, `dev/lint-java` keeps Java code healthy and helps PR review by saving much time. This issue aims remove unused imports from Java/Scala code and add `UnusedImports` checkstyle rule to help developers. ## How was this patch tested? ``` ./dev/lint-java ./build/sbt compile ``` Author: Dongjoon Hyun <dongjoon@apache.org> Closes #11438 from dongjoon-hyun/SPARK-13583.
* [SPARK-13423][WIP][CORE][SQL][STREAMING] Static analysis fixes for 2.xSean Owen2016-03-037-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Make some cross-cutting code improvements according to static analysis. These are individually up for discussion since they exist in separate commits that can be reverted. The changes are broadly: - Inner class should be static - Mismatched hashCode/equals - Overflow in compareTo - Unchecked warnings - Misuse of assert, vs junit.assert - get(a) + getOrElse(b) -> getOrElse(a,b) - Array/String .size -> .length (occasionally, -> .isEmpty / .nonEmpty) to avoid implicit conversions - Dead code - tailrec - exists(_ == ) -> contains find + nonEmpty -> exists filter + size -> count - reduce(_+_) -> sum map + flatten -> map The most controversial may be .size -> .length simply because of its size. It is intended to avoid implicits that might be expensive in some places. ## How was the this patch tested? Existing Jenkins unit tests. Author: Sean Owen <sowen@cloudera.com> Closes #11292 from srowen/SPARK-13423.

* [SPARK-13457][SQL] Removes DataFrame RDD operationsCheng Lian2016-02-276-8/+9
| | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This is another try of PR #11323. This PR removes DataFrame RDD operations except for `foreach` and `foreachPartitions` (they are actions rather than transformations). Original calls are now replaced by calls to methods of `DataFrame.rdd`. PR #11323 was reverted because it introduced a regression: both `DataFrame.foreach` and `DataFrame.foreachPartitions` wrap underlying RDD operations with `withNewExecutionId` to track Spark jobs. But they are removed in #11323. ## How was the this patch tested? No extra tests are added. Existing tests should do the work. Author: Cheng Lian <lian@databricks.com> Closes #11388 from liancheng/remove-df-rdd-ops.

| | | | | | | | | | | | | | | | | | | and change tracking function signature SPARK-12244: Based on feedback from early users and personal experience attempting to explain it, the name trackStateByKey had two problem. "trackState" is a completely new term which really does not give any intuition on what the operation is the resultant data stream of objects returned by the function is called in docs as the "emitted" data for the lack of a better. "mapWithState" makes sense because the API is like a mapping function like (Key, Value) => T with State as an additional parameter. The resultant data stream is "mapped data". So both problems are solved. SPARK-12245: From initial experiences, not having the key in the function makes it hard to return mapped stuff, as the whole information of the records is not there. Basically the user is restricted to doing something like mapValue() instead of map(). So adding the key as a parameter.

TBD: [updated] no fix for now per discussion. `org.apache.spark.mllib.classification.LogisticRegressionModel` `public scala.Option<java.lang.Object> getThreshold();` has wrong return type for Java invocation. `SVMModel` has the similar issue.

* [SPARK-12084][CORE] Fix codes that uses ByteBuffer.array incorrectlyShixiong Zhu2015-12-041-1/+4
| | | | | | | | | | `ByteBuffer` doesn't guarantee all contents in `ByteBuffer.array` are valid. E.g, a ByteBuffer returned by `ByteBuffer.slice`. We should not use the whole content of `ByteBuffer` unless we know that's correct. This patch fixed all places that use `ByteBuffer.array` incorrectly. Author: Shixiong Zhu <shixiong@databricks.com> Closes #10083 from zsxwing/bytebuffer-array.
