------------------------------------------

             Summary: check for edit log corruption at the end of the log
                 Key: HDFS-3335
                 URL: https://issues.apache.org/jira/browse/HDFS-3335
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 0.23.0
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe


Even after encountering an OP_INVALID, we should check the end of the edit log 
to make sure that it contains no more edits.

This will catch things like rare race conditions or log corruptions that would 
otherwise remain undetected.  They will got from being silent data loss 
scenarios to being cases that we can detect and fix.

Using recovery mode, we can choose to ignore the end of the log if necessary.
