-----------------------------------
Summary: Master heap setting in distributed mode should be limited
Key: AMBARI-13161
URL: https://issues.apache.org/jira/browse/AMBARI-13161
Project: Ambari
Issue Type: Task
Components: ambari-metrics, stacks
Affects Versions: 2.1.2
Reporter: Dmytro Sen
Assignee: Dmytro Sen
Priority: Critical
Fix For: 2.1.2
Attachments: AMBARI-13161.patch
- stack advisor allocated 713m to Master and 1024m to RS, in distributed mode.
For small clusters we should default to 512m Master, RS should get as much
memory as possible.
- In distributed mode we should WARN if no DN is local and set
dfs.client.read.shortcircuit = true in ams-hbase-site if local DN is present
