[jira] [Created] (YARN-9259) Assign ApplicationMaster (AM) Memory Based on Container Size

BELUGA BEHR created YARN-9259:
---------------------------------

             Summary: Assign ApplicationMaster (AM) Memory Based on Container Size
                 Key: YARN-9259
                 URL: https://issues.apache.org/jira/browse/YARN-9259
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: BELUGA BEHR


[YARN-7936] introduced a sane default value for the ApplicationMaster (AM) Java heap size.  However, [MAPREDUCE-5785] added a feature that sets the Java Heap size of the Mapper/Reducer to be 80% (configurable, of course) of the YARN container size.

Please add similar logic for MR ApplicationMaster.  If the size of the AM container is increased, the JVM heap size should be too automatically.
