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

             Summary: Verify open files captured in the snapshots across config disable and
enable
                 Key: HDFS-12730
                 URL: https://issues.apache.org/jira/browse/HDFS-12730
             Project: Hadoop HDFS
          Issue Type: Test
          Components: hdfs
    Affects Versions: 3.0.0
            Reporter: Manoj Govindassamy
            Assignee: Manoj Govindassamy


Open files captured in the snapshots have their meta data preserved based on the config 
_dfs.namenode.snapshot.capture.openfiles_ (refer HDFS-11402). It is possible for the NameNode
to get restarted with config turned on or off and the attributes of the open files captured
in the snapshots are influenced accordingly. Better to have a test case to verify open file
attributes across config turn on and off, and the current expected behavior with HDFS-11402
so as to catch any regressions in the future.
