> Key: HBASE-1101
> URL: https://issues.apache.org/jira/browse/HBASE-1101
> Project: Hadoop HBase
> Issue Type: Bug

> Fix For: 0.19.0

> 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.
