------------------------------------------
Summary: Warn if Xmn size is oversubscribed in AMS HBase master
and region server config
Key: AMBARI-13643
URL: https://issues.apache.org/jira/browse/AMBARI-13643
Project: Ambari
Issue Type: Bug
Components: ambari-metrics
Affects Versions: 2.1.2
Reporter: Aravindan Vijayan
Assignee: Aravindan Vijayan
Priority: Critical
Problem/Bug
While setting the AMS configuration, the user can set any unbounded value for
the Xmn settings. This might lead to undesirable outcomes from the JVM.
Fix
Provide validation of Xmn settings based on AMS mode.
If AMS is operating in embedded mode
regionserver_xmn ---- 12-20% of ( hbase_master_heapsize +
hbase_regionserver_heapsize)
If AMS is operating in distributed distributed mode
hbase_master_xmn ---- 12 - 20% of hbase_master_heapsize
regionserver_xmn ---- 12 - 20% of hbase_regionserver_heapsize
