Subject [jira] [Created] (AMBARI-19573) Increase max limit for -Xmn parameter
Date Mon, 16 Jan 2017 22:01:26 GMT
Ted Yu created AMBARI-19573:
-------------------------------

             Summary: Increase max limit for -Xmn parameter
                 Key: AMBARI-19573
                 URL: https://issues.apache.org/jira/browse/AMBARI-19573
             Project: Ambari
          Issue Type: Improvement
            Reporter: Ted Yu


Currently, max value for -Xmn parameter is bounded by (hbase-rs-2.2.json):
{code}
            "hbase_regionserver_xmn_max": "512",
{code}
During multiple troubleshooting sessions with customers, we (thanks to [~vrodionov]) found
that this limit is too low for large heap size.

This JIRA is to increase the limit to 4000 MB.
