Summary: Implement a heuristic to auto-size Java heap of MRAppMaster container Key: MAPREDUCE-6209 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6209 Project: Hadoop Map/Reduce Issue Type: Improvement Components: applicationmaster Reporter: Gera Shegalov The size of Java heap required by the AM is linearly proportional to the size of the MR job (number of mappers/splits and reducers). it would be nice if users did not have to adjust the AM container size when transitioning from testing job on a small sample to a production job on a full-scale dataset. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
