[jira] [Created] (HBASE-13516) Increase PermSize to 128MB

Enis Soztutar created HBASE-13516:
-------------------------------------

             Summary: Increase PermSize to 128MB
                 Key: HBASE-13516
                 URL: https://issues.apache.org/jira/browse/HBASE-13516
             Project: HBase
          Issue Type: Improvement
            Reporter: Enis Soztutar
            Assignee: Enis Soztutar
             Fix For: 2.0.0, 1.1.0


HBase uses ~40MB, and with Phoenix we use ~56MB of Perm space out of 64MB by default. Every Filter and Coprocessor increases that.

Running out of perm space triggers a stop the world full GC of the entire heap. We have seen this in misconfigured cluster. 

Should we default to  {{-XX:PermSize=128m -XX:MaxPermSize=128m}} out of the box as a convenience for users?
