      Description

      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.
