Subject [jira] [Created] (HDFS-5568) Support inclusion of snapshot paths in Namenode fsck
Date Tue, 26 Nov 2013 04:50:36 GMT
Vinay created HDFS-5568:
---------------------------

             Summary: Support inclusion of snapshot paths in Namenode fsck
                 Key: HDFS-5568
                 URL: https://issues.apache.org/jira/browse/HDFS-5568
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: snapshots
            Reporter: Vinay
            Assignee: Vinay


Support Fsck to check the snapshot paths also for inconsistency.

Currently Fsck supports snapshot paths if path given explicitly refers to a snapshot path.

We have seen safemode problems in our clusters which were due to blocks missing which were
only present inside snapshots. But "hdfs fsck /" shows HEALTHY. 

So supporting snapshot paths also during fsck (may be by default or on demand) would be helpful
in these cases instead of specifying each and every snapshottable directory.
