--------------------------------------
Sorry for the late response, [~anoop.hbase] and [[email protected]]. I think
Anoop mentioned the read path, how about the write path? Does the write path
use the DBB? To me, the issue we run into is when the replication sink trying
to send the batch to the final region server, thanks.

> 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.
