Merge pull request #173 from kayousterhout/scheduler_hang

Fix bug where scheduler could hang after task failure.

When a task fails, we need to call reviveOffers() so that the
task can be rescheduled on a different machine. In the current code,
the state in ClusterTaskSetManager indicating which tasks are
pending may be updated after revive offers is called (there's a
race condition here), so when revive offers is called, the task set
manager does not yet realize that there are failed tasks that need
to be relaunched.

This isn't currently unit tested but will be once my pull request for
merging the cluster and local schedulers goes in -- at which point
many more of the unit tests will exercise the code paths through
the cluster scheduler (currently the failure test suite uses the local
scheduler, which is why we didn't see this bug before).

Don't retry tasks when they fail due to a NotSerializableException

As with my previous pull request, this will be unit tested once the Cluster and Local schedulers get merged.

Merge pull request #153 from ankurdave/stop-spot-cluster

Enable stopping and starting a spot cluster

Clusters launched using `--spot-price` contain an on-demand master and spot slaves. Because EC2 does not support stopping spot instances, the spark-ec2 script previously could only destroy such clusters.

This pull request makes it possible to stop and restart a spot cluster.
* The `stop` command works as expected for a spot cluster: the master is stopped and the slaves are terminated.
* To start a stopped spot cluster, the user must invoke `launch --use-existing-master`. This launches fresh spot slaves but resumes the existing master.

Merge pull request #165 from NathanHowell/kerberos-master

spark-assembly.jar fails to authenticate with YARN ResourceManager

The META-INF/services/ sbt MergeStrategy was discarding support for Kerberos, among others. This pull request changes to a merge strategy similar to sbt-assembly's default. I've also included an update to sbt-assembly 0.9.2, a minor fix to it's zip file handling.

Merge pull request #137 from tgravescs/sparkYarnJarsHdfsRebase

Allow spark on yarn to be run from HDFS.

Allows the spark.jar, app.jar, and log4j.properties to be put into hdfs.  Allows you to specify the files on a different hdfs cluster and it will copy them over. It makes sure permissions are correct and makes sure to put things into public distributed cache so they can be reused amongst users if their permissions are appropriate.  Also add a bit of error handling for missing arguments.
