Description

https://issues.apache.org/jira/browse/HADOOP-4420 (which also fixes https://issues.apache.org/jira/browse/HADOOP-4419) gracefully handles null ptr exceptions if JobTracker.setJobPriority() and killJob() get a null reference back from JobID lookup by returning silently. Future versions, though, should throw a better exception back to the client (see this comment: https://issues.apache.org/jira/browse/HADOOP-4419?focusedCommentId=12639889#action_12639889) so they can handle the problem.

This JIRA is for the separate issue of the API change that would require.
