I recently tried to update one of our clusters to a version of 0.94.2 seen here: https://github.com/stumbleupon/hbase/commits/su_prod_94
When doing that all of the nodes started taking all available cpu time. Not much interesting was in the logs however jstacks looked like this: http://pastebin.com/raw.php?i=fw6P5RKE Everything is spinning in scans. A version of 0.94.1 works perfectly and reverting solved all issues. I don't really have enough data to point at any jira as the cause I was just wondering if anyone had some insight into the few commits between 0.94.1 release and the head of the above github that could cause scans to spin. Thanks
