    Description

      HDFS-8143 changed Mover to exit after some retry when failed to move blocks. Two additional suggestions:

      1. Mover retry counter should be incremented only if all moves fail. If there are some successful moves, the counter should be reset.
      2. Mover should exit with NO_MOVE_PROGRESS instead of IO_EXCEPTION in case of failure.
