NPE in HConnectionManager$TableServers.processBatchOfRows

Had DFS errors take down a region server. Looks like a full restart may be necessary because errors on the region continue. Clients attempting to store to the region get a NPE in HConnectionManager$TableServers.processBatchOfRows.

Caused by: java.lang.NullPointerException
