* [SPARK-12212][ML][DOC] Clarifies the difference between spark.ml, ↵Timothy Hunter2015-12-1031-1793/+149
| | | | | | | | | | | | spark.mllib and mllib in the documentation. Replaces a number of occurences of `MLlib` in the documentation that were meant to refer to the `spark.mllib` package instead. It should clarify for new users the difference between `spark.mllib` (the package) and MLlib (the umbrella project for ML in spark). It also removes some files that I forgot to delete with #10207 Author: Timothy Hunter <timhunter@databricks.com> Closes #10234 from thunterdb/12212.

* [SPARK-12081] Make unified memory manager work with small heapsAndrew Or2015-12-012-3/+3
| | | | | | | | | | The existing `spark.memory.fraction` (default 0.75) gives the system 25% of the space to work with. For small heaps, this is not enough: e.g. default 1GB leaves only 250MB system memory. This is especially a problem in local mode, where the driver and executor are crammed in the same JVM. Members of the community have reported driver OOM's in such cases. **New proposal.** We now reserve 300MB before taking the 75%. For 1GB JVMs, this leaves `(1024 - 300) * 0.75 = 543MB` for execution and storage. This is proposal (1) listed in the [JIRA](https://issues.apache.org/jira/browse/SPARK-12081).

| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
