[jira] Created: (HADOOP-4725) jobID() lookup failure should notify client

jobID() lookup failure should notify client
-------------------------------------------

                 Key: HADOOP-4725
                 URL: https://issues.apache.org/jira/browse/HADOOP-4725
             Project: Hadoop Core
          Issue Type: Improvement
          Components: mapred
    Affects Versions: 0.19.1
            Reporter: Aaron Kimball
            Priority: Minor
             Fix For: 0.20.0


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.
