> HDFS-8143 changed Mover to exit after some retry when failed to move blocks.  Two additional
suggestions:
> # Mover retry counter should be incremented only if all moves fail.  If there are some
successful moves, the counter should be reset.
> # Mover should exit with NO_MOVE_PROGRESS instead of IO_EXCEPTION in case of failure.
