Description

In this patch, I am adding 2 tests and a test util class.

1) TestHAFailover: Fails over between the NameNodes a configurable number of times. Checks the service state of each NN after each failover to ensure that the service state is correct.

2) TestKilLNNFailover: Kills the Active NN. Waits and fails over to the standby NN. Waits and checks that the former standby is now active. Restarts the killed NN and checks that it is now standby. Goes through this process a configurable number of times.

3) HATestUtil: Helper methods to fail over and kill the NameNodes.
