* [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-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-15290][BUILD] Move annotations, like @Since / @DeveloperApi, into ↵Sean Owen2016-05-171-1/+1
| | | | | | | | | | | | | | | | | | 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-14011][CORE][SQL] Enable `LineLength` Java checkstyle ruleDongjoon Hyun2016-03-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? [Spark Coding Style Guide](https://cwiki.apache.org/confluence/display/SPARK/Spark+Code+Style+Guide) has 100-character limit on lines, but it's disabled for Java since 11/09/15. This PR enables **LineLength** checkstyle again. To help that, this also introduces **RedundantImport** and **RedundantModifier**, too. The following is the diff on `checkstyle.xml`. ```xml - <!-- TODO: 11/09/15 disabled - the lengths are currently > 100 in many places --> - <!-- <module name="LineLength"> <property name="max" value="100"/> <property name="ignorePattern" value="^package.*|^import.*|a href|href|http://|https://|ftp://"/> </module> - --> <module name="NoLineWrap"/> <module name="EmptyBlock"> <property name="option" value="TEXT"/> -167,5 +164,7 </module> <module name="CommentsIndentation"/> <module name="UnusedImports"/> + <module name="RedundantImport"/> + <module name="RedundantModifier"/> ``` ## How was this patch tested? Currently, `lint-java` is disabled in Jenkins. It needs a manual test. After passing the Jenkins tests, `dev/lint-java` should passes locally.

Currently, when we run `./dev/lint-java`, it shows the error. ``` Checkstyle checks failed at following occurrences: [ERROR] src/main/java/org/apache/spark/util/sketch/CountMinSketch.java:[53,10] (modifier) ModifierOrder: 'public' modifier out of order with the JLS suggestions. ``` ## How was this patch tested? ``` $ ./dev/lint-java Checkstyle checks passed. ``` Author: Dongjoon Hyun <dongjoon@apache.org> Closes #11390 from dongjoon-hyun/fix_modifier_order.

* [SPARK-6363][BUILD] Make Scala 2.11 the default Scala versionJosh Rosen2016-01-301-2/+2
| | | | | | | | | | | | 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. Author: Josh Rosen <joshrosen@databricks.com> Closes #10608 from JoshRosen/SPARK-6363.

| | | | | | | | This PR is a follow-up of #10911. It adds specialized update methods for `CountMinSketch` so that we can avoid doing internal/external row format conversion in `DataFrame.countMinSketch()`. Author: Cheng Lian <lian@databricks.com> Closes #10968 from liancheng/cms-specialized.
* [SPARK-12938][SQL] DataFrame API for Bloom filterWenchen Fan2016-01-274-91/+179
| | | | | | | | | | This PR integrates Bloom filter from spark-sketch into DataFrame. This version resorts to RDD.aggregate for building the filter. A more performant UDAF version can be built in future follow-up PRs. This PR also add 2 specify `put` version(`putBinary` and `putLong`) into `BloomFilter`, which makes it easier to build a Bloom filter over a `DataFrame`.

* [SPARK-12936][SQL] Initial bloom filter implementationWenchen Fan2016-01-255-0/+602
| | | | | | | | | | | | | This PR adds an initial implementation of bloom filter in the newly added sketch module. The implementation is based on the [`BloomFilter` class in guava](https://code.google.com/p/guava-libraries/source/browse/guava/src/com/google/common/hash/BloomFilter.java). Some difference from the design doc: * expose `bitSize` instead of `sizeInBytes` to user. * always need the `expectedInsertions` parameter when create bloom filter. Author: Wenchen Fan <wenchen@databricks.com> Closes #10883 from cloud-fan/bloom-filter.

* [SPARK-12933][SQL] Initial implementation of Count-Min sketchCheng Lian2016-01-236-0/+852
This PR adds an initial implementation of count min sketch, contained in a new module spark-sketch under `common/sketch`. The implementation is based on the [`CountMinSketch` class in stream-lib][1]. As required by the [design doc][2], spark-sketch should have no external dependency. Two classes, `Murmur3_x86_32` and `Platform` are copied to spark-sketch from spark-unsafe for hashing facilities. They'll also be used in the upcoming bloom filter implementation. The following features will be added in future follow-up PRs: - Serialization support - DataFrame API integration [1]: https://github.com/addthis/stream-lib/blob/aac6b4d23a8686b000f80baa447e0922ecac3bcb/src/main/java/com/clearspring/analytics/stream/frequency/CountMinSketch.java [2]: https://issues.apache.org/jira/secure/attachment/12782378/BloomFilterandCount-MinSketchinSpark2.0.pdf Author: Cheng Lian <lian@databricks.com> Closes #10851 from liancheng/count-min-sketch.
