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.
