NameNode could delete wrong edits file when there is an error
-------------------------------------------------------------
Key: HADOOP-2460
URL: https://issues.apache.org/jira/browse/HADOOP-2460
Project: Hadoop
Issue Type: Bug
Components: dfs
Affects Versions: 0.15.0
Reporter: Raghu Angadi
Assignee: dhruba borthakur
Fix For: 0.15.2
On one of the clusters two namenode directories were specified. The second
directory had errors and edits log sync failed. Namenode was supposed to run
with the good directory, but it exited with a 'fatal error' message.
Looks like it is caused by a bug in {{processIOError()}} in FSEditsLog.java. It
removes the wrong directory since it passes in index into {{errorStreams}}
rather than index into {{editStreams}} by mistake.
This probably should go in 0.15.2.
