[jira] [Updated] (HBASE-16195) Should not add chunk into chunkQueue if not using chunk pool in HeapMemStoreLAB

["Yu Li (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-16195?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yu Li updated HBASE-16195:
--------------------------
    Attachment: HBASE-16195.patch

The initial patch:
1. Change to only initialize and use chunkQueue when chunkPool is in use.
2. Limit chunkQueue length, max allowed memory taken by chunk queue is memstore flush size by default. Introduced property {{hbase.hregion.memstore.mslab.chunkqueue.length}} to set it.
3. Remove the chunk from chunkQueue after retiring it. Notice that chunkPool might be full in which case the {{putbackChunks}} call won't be able to clear chunkQueue, so we should remove the chunk explicitly.
