* [SPARK-12000] Fix API doc generation issuesJosh Rosen2015-11-301-3/+3
| | | | | | | | | | | | | | | This pull request fixes multiple issues with API doc generation. - Modify the Jekyll plugin so that the entire doc build fails if API docs cannot be generated. This will make it easy to detect when the doc build breaks, since this will now trigger Jenkins failures. - Change how we handle the `-target` compiler option flag in order to fix `javadoc` generation. - Incorporate doc changes from thunterdb (in #10048). Closes #10048. Author: Josh Rosen <joshrosen@databricks.com> Author: Timothy Hunter <timhunter@databricks.com> Closes #10049 from JoshRosen/fix-doc-build.

* [SPARK-11140][CORE] Transfer files using network lib when using NettyRpcEnv.Marcelo Vanzin2015-11-232-2/+5
| | | | | | | | | | | | | | | | This change abstracts the code that serves jars / files to executors so that each RpcEnv can have its own implementation; the akka version uses the existing HTTP-based file serving mechanism, while the netty versions uses the new stream support added to the network lib, which makes file transfers benefit from the easier security configuration of the network library, and should also reduce overhead overall. The change includes a small fix to TransportChannelHandler so that it propagates user events to downstream handlers. Author: Marcelo Vanzin <vanzin@cloudera.com> Closes #9530 from vanzin/SPARK-11140.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | are masked by functions with same name in SparkR Added tests for function that are reported as masked, to make sure the base:: or stats:: function can be called. For those we can't call, added them to SparkR programming guide. It would seem to me `table, sample, subset, filter, cov` not working are not actually expected - I investigated/experimented with them but couldn't get them to work. It looks like as they are defined in base or stats they are missing the S3 generic, eg. ``` > methods("transform") [1] transform,ANY-method transform.data.frame [3] transform,DataFrame-method transform.default see '?methods' for accessing help and source code > methods("subset") [1] subset.data.frame subset,DataFrame-method subset.default [4] subset.matrix see '?methods' for accessing help and source code Warning message: In .S3methods(generic.function, class, parent.frame()) : function 'subset' appears not to be S3 generic; found functions that look like S3 methods ``` Any idea?

* [SPARK-11089][SQL] Adds option for disabling multi-session in Thrift serverCheng Lian2015-11-171-0/+14
| | | | | | | | | | This PR adds a new option `spark.sql.hive.thriftServer.singleSession` for disabling multi-session support in the Thrift server. Note that this option is added as a Spark configuration (retrieved from `SparkConf`) rather than Spark SQL configuration (retrieved from `SQLConf`). This is because all SQL configurations are session-ized. Since multi-session support is by default on, no JDBC connection can modify global configurations like the newly added one.

* [SPARK-6152] Use shaded ASM5 to support closure cleaning of Java 8 compiled ↵Josh Rosen2015-11-111-0/+4
| | | | | | | | | | | | | | | | classes This patch modifies Spark's closure cleaner (and a few other places) to use ASM 5, which is necessary in order to support cleaning of closures that were compiled by Java 8. In order to avoid ASM dependency conflicts, Spark excludes ASM from all of its dependencies and uses a shaded version of ASM 4 that comes from `reflectasm` (see [SPARK-782](https://issues.apache.org/jira/browse/SPARK-782) and #232). This patch updates Spark to use a shaded version of ASM 5.0.4 that was published by the Apache XBean project; the POM used to create the shaded artifact can be found at https://github.com/apache/geronimo-xbean/blob/xbean-4.4/xbean-asm5-shaded/pom.xml. http://movingfulcrum.tumblr.com/post/80826553604/asm-framework-50-the-missing-migration-guide was a useful resource while upgrading the code to use the new ASM5 opcodes. I also added a new regression tests in the `java8-tests` subproject; the existing tests were insufficient to catch this bug, which only affected Scala 2.11 user code which was compiled targeting Java 8.
