Our testdata/run-all.sh can be brittle depending on the state of your Hdfs.
In particular, Yarn depends on the NN not being in safe mode, but it may take
some time for the NN to exit safe mode immediately after starting Hdfs.
This patch makes the NN startup script complete only after the NN has exited
safe mode.

Since we're no longer using the MiniLlama, we need to explicitly set
whether or not the cluster is pseudo-distributed. Impala needs this
information to correctly translate datanode addresses to a format that
Llama understands.
This change (adapted from one made by Casey) adds a method to the
frontend (callable via JNI) to get a configuration value from the Hadoop
configuration. We'll set that configuration value for local RM testing.

The hdfs-site template in CDH5 is different from the one we fine in CDH5. Specifically:
- It has entries that enable hdfs caching.
- It uses the correct parameter name for hdfs block locations timeout.

This should allow individual service components, such as a single nodemanager,
to be shutdown for failure testing. The mini-cluster bundled with hadoop is a
single process that does not expose the ability to control individual roles.
Now each role can be controlled and configured independently of the others.
