Jeremy Carroll commented on HBASE-15513: ---------------------------------------- Looking for guidance on this as well. We are still running CMS due to the fact that we could not get G1GC latency under ~100ms (max). So is the advice to set to 1, and disable heap auto tuning? > hbase.hregion.memstore.chunkpool.maxsize is 0.0 by default > ---------------------------------------------------------- > > Key: HBASE-15513 > URL: https://issues.apache.org/jira/browse/HBASE-15513 > Project: HBase > Issue Type: Sub-task > Affects Versions: 2.0.0 > Reporter: Vladimir Rodionov > Assignee: Vladimir Rodionov > Fix For: 2.0.0 > > Attachments: HBASE-15513-v1.patch > > > That results in excessive MemStoreLAB chunk allocations because we can not > reuse them. Not sure, why it has been disabled, by default. May be the code > has not been tested well? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
