[hbase] Unexpected exits corrupt DFS
------------------------------------
Key: HADOOP-2749
URL: https://issues.apache.org/jira/browse/HADOOP-2749
Project: Hadoop Core
Issue Type: Bug
Components: contrib/hbase
Reporter: Bryan Duxbury
Fix For: 0.17.0
When a RegionServer exits unexpectedly, it often leaves its DFS files open. In
the case of the redo log, this can result in a zero-length file, which a newly
started RegionServer will be unable to read, causing it to exit again. It also
causes DFS corruption, requiring the admin to run a dfs fsck -delete before
HBase can be restarted.
