--------------------------------------------
Thanks, [~huaxiang] for the note. Users started hitting this issue, for

> Recently we run into a direct memory leak case, which takes some time to
> trace and debug. Internally discussed with our [[email protected]], we
> thought we had some findings and want to share with the community.
> Basically, it is the issue described in
> http://www.evanjones.ca/java-bytebuffer-leak.html and it happened to one of
> our hbase clusters.
> Create the jira first and will fill in more details later.
