[jira] [Commented] (HBASE-10374) add jemalloc into the choice of memstore allocation

    [ https://issues.apache.org/jira/browse/HBASE-10374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13875022#comment-13875022 ] 

stack commented on HBASE-10374:
-------------------------------

[~jianbginglover] What you thinking?  We pull in netty4, redo our core on top of it (smile), then as a side benefit, use their jemalloc implementation for block cache?  Poking around, I don't see it here http://netty.io/4.0/api/index.html  Thanks.
