Subject [jira] [Updated] (MAPREDUCE-6776) yarn.app.mapreduce.client.job.max-retries should have a more useful default
Date Mon, 12 Sep 2016 21:42:20 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-6776?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Daniel Templeton updated MAPREDUCE-6776:
----------------------------------------
    Description: The default is 0, so any communication failure 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.  (was: 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.)
