Description

testMRAppMasterMissingStaging will sometimes cause the JVM to exit due to this error from AsyncDispatcher:

2013-01-05 02:14:54,682 FATAL [AsyncDispatcher event handler] event.AsyncDispatcher (AsyncDispatcher.java:dispatch(137)) - Error in dispatcher thread
java.lang.Exception: No handler for registered for class org.apache.hadoop.mapreduce.jobhistory.EventType, cannot deliver EventType: AM_STARTED
        at org.apache.hadoop.yarn.event.AsyncDispatcher.dispatch(AsyncDispatcher.java:132)
        at org.apache.hadoop.yarn.event.AsyncDispatcher$1.run(AsyncDispatcher.java:77)
        at java.lang.Thread.run(Thread.java:662)
2013-01-05 02:14:54,682 INFO  [AsyncDispatcher event handler] event.AsyncDispatcher (AsyncDispatcher.java:dispatch(140)) - Exiting, bbye..

This can cause a build to fail since the test process exits without unregistering from surefire which treats it as a build error rather than a test failure.
