Subject [jira] [Created] (HDFS-6384) Provide an alternative offline file system analysis tool
Date Tue, 13 May 2014 16:01:15 GMT
Kihwal Lee created HDFS-6384:
--------------------------------

             Summary: Provide an alternative offline file system analysis tool
                 Key: HDFS-6384
                 URL: https://issues.apache.org/jira/browse/HDFS-6384
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.5.0
            Reporter: Kihwal Lee
            Priority: Critical


Per discussion in HDFS-6293, we need an alternative way of analyzing file system offline.
 Some use cases can be covered by post-processing the new PB-based fsimage without consuming
much resources, but others may need a way to efficiently generating fully constructed name
space.

Once we have a better solution, we should deprecate NN's ability to save its partial state
in the old fsimage format.
