    Description

      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.
