Brahma Reddy Battula created HDFS-13840:
-------------------------------------------

             Summary: RBW Blocks which are having less GS shouldn't added on DN restart
                 Key: HDFS-13840
                 URL: https://issues.apache.org/jira/browse/HDFS-13840
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Brahma Reddy Battula
            Assignee: Brahma Reddy Battula


# Start two DN's  (DN1,DN2).
 # Write fileA with rep=2 ( dn't close)
 # Stop DN1.
 # Write some data to fileA.
 # restart the DN1
 # Get the blocklocations of fileA.

Here RWR state block will be reported on DN restart and added to locations.

IMO,RWR blocks which having less GS shouldn't added, as they give false postive (anyway read
can be failed as it's genstamp is less)
