huaxiang sun commented on HBASE-19320:
--------------------------------------

thanks [~saint....@gmail.com] for review. It needs some manual work as the fix 
from JDK only applies to JDK8u102+, enable it by default sometimes may work 
(sometimes may not if jvm version is not right).

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