Description

Observed on Hudson:

java.lang.NullPointerException
	at org.apache.hadoop.mapred.JobInProgress.terminateJob(JobInProgress.java:2117)

This was introduced by HADOOP-5565. FakeJobInProgress doesn't pass a JobTracker reference to the subtype cstr, so calling kill() derefs the null JT field.
