We were caught by this issue.  It impacted all of our JVM processes, 
including the full hbase/zookeeper/HDFS stack.

Before we had determined root cause, we somewhat hastily bounced some of 
our services (ZK, HM), and had to forcefully kill a few RSes in an 
attempt to get things back online.

At the end of the day (with root cause addressed), I was thrilled to see 
that our hbase cluster came back online, split logs for 10 minutes, then 
passed hbck as soon as all the regions were available.  It is very 
impressive that hbase is capable of withstanding what amounted to a 
pretty nasty scenario without data loss.

Nice work, guys.
