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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
