[jira] [Created] (YARN-4346) Test committer.commitJob() behavior during committing when MR AM get failed.

Junping Du created YARN-4346:
--------------------------------

             Summary: Test committer.commitJob() behavior during committing when MR AM get failed.
                 Key: YARN-4346
                 URL: https://issues.apache.org/jira/browse/YARN-4346
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Junping Du


In MAPREDUCE-5485, we are adding additional API (isCommitJobRepeatable) to allow job commit can tolerate AM failure in some cases (like FileOutputCommitter in v2 algorithm). Although we have unit test to cover most of flows, we may want a completed end to end test to verify the whole work flow.
The scenario include:
1. For FileOutputCommitter (or some sub class), emulate a MR AM failure or restart during commitJob() in progress
2. Check different behavior for v1 and v2 (support isCommitJobRepeatable() or not)
