>From #hbase:

[13:01] <jdcryans>      apurtell: you should remove my comment in the first 
line of processBatchOfRows
[13:01] <apurtell>      jdcryans: ok
[13:02] <jdcryans>      apurtell: also the method is very long now... I would 
either chop it or add comments
[13:03] <jdcryans>      apurtell: I would try to refactor all the: while 
(currentRegion == null && tries < numRetries) {
[13:04] <jdcryans>      something like getRegionNameWithRetries
[13:04] <apurtell>      jdcryans: ok

> 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
