Recently we run into a direct memory leak case, which takes some time to trace and debug. Internally discussed with our [~saint.ack@gmail.com], 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.
