Subject [jira] [Commented] (HBASE-14921) Memory optimizations
Date Wed, 30 Mar 2016 10:55:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14921?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15217795#comment-15217795

ramkrishna.s.vasudevan commented on HBASE-14921:

bq.This would be a problem. What is the case when ChunkPool need to be reset and initialized?
I mean the reset and init of Chunk not the pool itself. Anyway you can ignore this. I did
not have the code with me that day. 
But one qusetion why is that the init() method position changed now? When a chunk was got
from the pool the init was previously happening after the CAS operation but now it is now
moved into the allocateChunk itself?  Will it have ramifications?
