Subject [jira] [Updated] (MAPREDUCE-6776) yarn.app.mapreduce.client.job.max-retries should have a more useful default
Date Fri, 07 Oct 2016 21:53:22 GMT

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

Robert Kanter updated MAPREDUCE-6776:
       Resolution: Fixed
     Hadoop Flags: Incompatible change,Reviewed
    Fix Version/s: 3.0.0-alpha2
     Release Note: The default value of yarn.app.mapreduce.client.job.max-retries has been
changed from 0 to 3.  This will help protect clients from failures that are transient.  True
failures may take slightly longer now due to the retries.
           Status: Resolved  (was: Patch Available)

Thanks [~miklos.szegedi@cloudera.com] and everyone.  Committed to trunk and branch-2!

> 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.
