Mark Hamstra 934a53c8b6 Change docs on 'reduce' since the merging of local reduces no longer preserves 
ordering, so the reduce function must also be commutative.

Stephen Haberman a9c8d53cfa Clean up RDDs, mainly to use getSplits. 
Also made sure clearDependencies() was calling super, to ensure
the getSplits/getDependencies vars in the RDD base class get
cleaned up.

Stephen Haberman 0e19093fd8 Handle Terminated to avoid endless DeathPactExceptions. 
Credit to Roland Kuhn, Akka's tech lead, for pointing out this
various obvious fix, but StandaloneExecutorBackend.preStart's
catch block would never (ever) get hit, because all of the
operation's in preStart are async.

So, the System.exit in the catch block was skipped, and instead
Akka was sending Terminated messages which, since we didn't
handle, it turned into DeathPactException, which started
a postRestart/preStart infinite loop.

Stephen Haberman 8bd0e888f3 Inline mergePair to look more like the narrow dep branch. 
No functionality changes, I think this is just more consistent
given mergePair isn't called multiple times/recursive.

Also added a comment to explain the usual case of having two parent RDDs.

Patrick Wendell 7eea64aa4c Streaming constructor which takes JavaSparkContext 
It's sometimes helpful to directly pass a JavaSparkContext,
and take advantage of the various constructors available for that.

Stephen Haberman 28e0cb9f31 Fix createActorSystem not actually using the systemName parameter. 
This meant all system names were "spark", which worked, but didn't
lead to the most intuitive log output.

This fixes createActorSystem to use the passed system name, and
refactors Master/Worker to encapsulate their system/actor names
instead of having the clients guess at them.

Note that the driver system name, "spark", is left as is, and is
still repeated a few times, but that seems like a separate issue.
