Allen Wittenauer commented on HDFS-9043:
----------------------------------------
bq. Shall we update the command to start-balancer.sh -policy which would be
common to both branch-2 and trunk
No, because sbin/* is mostly deprecated in trunk. This needs to be two
different patches for the two different branches.
