      Description

      We periodically see a situation where the regionserver process exists in the process list, zookeeper thread sends the keepalive so the master won't remove it from the active list, yet the regionserver will not serve data.

      Hadoop(cdh3u0), HBase 0.90.3 (Apache version), under load from an internal testing tool.
