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.
