    Description

      Steps to Repro :
      1. Start writing a EC file.
      2. After more than one stripe has been written, stop one datanode.
      3. Post pipeline recovery, keep on writing the data.
      4.Close the file.
      5. transition the namenode to standby and back to active.
      6. Turn on the shutdown datanode in step 2

      The BR from datanode 2 will make the block corrupt and during invalidate block won't remove it, since post failover the blocks would be on stale storage.
