Update default.parallelism docs, have StandaloneSchedulerBackend use it.
...
Only brand new RDDs (e.g. parallelize and makeRDD) now use default
parallelism, everything else uses their largest parent's partitioner
or partition size.

Added a unit test for cross-partition balancing in sort, and changes to
...
RangePartitioner to make it pass. It turns out that the first partition
was always kind of small due to how we picked partition boundaries.

Performance improvements to shuffle operations: in particular, preserve

RDD partitioning in more cases where it's possible, and use iterators
instead of materializing collections when doing joins.

Merge in engine improvements from the Spark Streaming project, developed

jointly with Tathagata Das and Haoyuan Li. This commit imports the changes
and ports them to Mesos 0.9, but does not yet pass unit tests due to
various classes not supporting a graceful stop() yet.

Some fixes to sorting for when the RDD has fewer elements than the

number of partitions we ask to partition it into. Also, removed a test
that was taking way too long to run.

Fix issue #65 : Change @serializable to extends Serializable in 2.9 branch
...
Note that we use scala.Serializable introduced in Scala 2.9 instead of
java.io.Serializable. Also, case classes inherit from scala.Serializable by
default.
