Daniel Templeton created MAPREDUCE-6776:
-------------------------------------------
Summary: yarn.app.mapreduce.client.job.max-retries should have a
more useful default
Key: MAPREDUCE-6776
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6776
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: client
Affects Versions: 2.8.0
Reporter: Daniel Templeton
Assignee: Daniel Templeton
The default is 0, so any communication results in a client failure. Oozie
doesn't like that. If the RM is failing over and Oozie gets a communication
failure, it assumes the target job has failed. I propose raising the default
to something modest like 3 or 5. The default retry interval is 2s.
