Vinay created HDFS-5427:
---------------------------

             Summary: not able to read deleted files from snapshot directly under snapshottable
dir after checkpoint and NN restart
                 Key: HDFS-5427
                 URL: https://issues.apache.org/jira/browse/HDFS-5427
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: snapshots
            Reporter: Vinay
            Assignee: Vinay


1. allow snapshots under dir /foo
2. create a file /foo/bar
3. create a snapshot s1 under /foo
4. wait till checkpoint or do saveNameSpace
5. restart NN.
6. Now try to read the file from snapshot /foo/.snapshot/s1/bar

client will get BlockMissingException


Reason is 
While loading the deleted file list for a snashottable dir from fsimage, blocks were not updated
in blocksmap
