Subject [jira] [Commented] (HBASE-16417) In-Memory MemStore Policy for Flattening and Compactions
Date Tue, 06 Dec 2016 08:10:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15724769#comment-15724769

Anoop Sam John commented on HBASE-16417:
----------------------------------------

I think there is some directly change needed now.. As per ur doc, the latest tests are with
no MSLAB itself..  2.0 now defaults to even having MSLAB pool on.  As u also doubted, the
G1GC initial heap occupancy factor and the BC + memstore size are the issues.   We should
set IHOP say 50% and then make sure BC + memstore size is under this.
