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.

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.

Stephen Haberman 12c1eb4756 Reduce the amount of duplicate logging Akka does to stdout. 
Given we have Akka logging go through SLF4j to log4j, we don't need
all the extra noise of Akka's stdout logger that is supposedly only
used during Akka init time but seems to continue logging lots of
noisy network events that we either don't care about or are in the
log4j logs anyway.

See:

http://doc.akka.io/docs/akka/2.0/general/configuration.html

    # Log level for the very basic logger activated during AkkaApplication startup
    # Options: ERROR, WARNING, INFO, DEBUG
    # stdout-loglevel = "WARNING"

Matei Zaharia 8b3041c723 Reduced the memory usage of reduce and similar operations 
These operations used to wait for all the results to be available in an
array on the driver program before merging them. They now merge values
incrementally as they arrive.
