The JIRA in question is actually reporting a bug with Shark, but I wanted to make sure Spark SQL did not have similar problems. This fixes a bug in our parsing code that was preventing the test from executing, but it looks like the RegexSerDe is working in Spark SQL.

This change replaces some Scala `for` and `foreach` constructs with `while` constructs. There may be a slight performance gain on the order of 1-2% when training an ALS model.
I trained an ALS model on the Movielens 10M-rating dataset repeatedly both with and without these changes. All 7 runs in both columns were done in a Scala `for` loop like this:
for (iter <- 0 to 10) {
val before = System.currentTimeMillis()
val model = ALS.train(rats, 20, 10)
val after = System.currentTimeMillis()
println("%d ms".format(after-before))
println("rmse %g".format(computeRmse(model, rats, numRatings)))
}
The timings were done on a multiuser machine, and I stopped one set of timings after 7 had been completed. It would be nice if somebody with dedicated hardware could confirm my timings.
After Before
121980 ms 122041 ms
117069 ms 117127 ms
115332 ms 117523 ms
115381 ms 117402 ms
114635 ms 116550 ms
114140 ms 114076 ms
112993 ms 117200 ms
Ratios are about 1.0005, 1.0005, 1.019, 1.0175, 1.01671, 0.99944, and 1.03723. I therefore suspect these changes make for a slight performance gain on the order of 1-2%.

2. Spark submit used deprecated environment variables (SPARK_CLASSPATH)

In the current implementation, the running job will hang if the DAGScheduler crashes for some reason (eventProcessActor throws exception in receive() )
The reason is that the actor will automatically restart when the exception is thrown during the running but is not captured properly (Akka behaviour), and the JobWaiters are still waiting there for the completion of the tasks
In this patch, I refactored the DAGScheduler with Akka and manage the eventProcessActor with supervisor, so that upon the failure of a eventProcessActor, the supervisor will terminate the EventProcessActor and close the SparkContext

This simplifies the shell a bunch and passes all arguments through to spark-submit.
There is a tiny incompatibility from 0.9.1 which is that you can't put `-c` _or_ `--cores`, only `--cores`. However, spark-submit will give a good error message in this case, I don't think many people used this, and it's a trivial change for users.
