Subject [jira] [Created] (MAPREDUCE-6456) Support configurable log aggregation policy
Date Wed, 19 Aug 2015 06:54:45 GMT
Ming Ma created MAPREDUCE-6456:

             Summary: Support configurable log aggregation policy
                 Key: MAPREDUCE-6456
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6456
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Ming Ma

YARN-221 provides a way for a YARN application to specify log aggregation policy via LogAggregationContext.

This jira covers the necessary changes in MR to use that feature so that any MR job can specify
its log aggregation policy via job configuration. That includes:

* Have MR define its own configurations to config these policies.
* Make code change at YarnRunner to retrieve these configurations and set the values via LogAggregationContext.
