Josh Rosen 33cd3a0c12 Remove map-side combining from ShuffleMapTask. 
This separation of concerns simplifies the 
ShuffleDependency and ShuffledRDD interfaces.

Map-side combining can be performed in a
mapPartitions() call prior to shuffling the RDD.

I don't anticipate this having much of a 
performance impact: in both approaches, each tuple
is hashed twice: once in the bucket partitioning
and once in the combiner's hashtable.  The same
steps are being performed, but in a different
order and through one extra Iterator.

Matei Zaharia ee2fcb2ce6 Added documentation to all the *RDDFunction classes, and moved them into 
the spark package to make them more visible. Also documented various
other miscellaneous things in the API.

Andy Konwinski d7363a6b8a Moves all files in core/src/main/scala/ that have RDD in their name 
from that directory to a new core/src/main/scala/rdd directory.

Matei Zaharia a96558caa3 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.

Matei Zaharia 63051dd2bc 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.

Ankur Dave 06637cb69e Fix PairRDDFunctions.groupWith partitioning 
This commit fixes a bug in groupWith that was causing it to destroy
partitioning information. It replaces a call to map with a call to
mapValues, which preserves partitioning.

Ismael Juma 0fba22b3d2 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.

Matei Zaharia 969644df8e Cleaned up a few issues to do with default parallelism levels. Also 
renamed HadoopFileWriter to HadoopWriter (since it's not only for files)
and fixed a bug for lookup().
