Reidddddd edited a comment on issue #468: HBASE-22822 : Un/Re-schedule balancer chore with balance_switch URL: https://github.com/apache/hbase/pull/468#issuecomment-520290804 IIRC, `gracefully_stop.sh` will turn balancer off, move regions, stop/restart RS, then turn balancer on. And there's one script `rolling_restart.sh` relying on `gracefully_stop.sh`, will repeat the mentioned process. If the RS number in rolling restart is large which is often the case in production env---hundreds at least, the master inside will cancel and remove task then construct a new task back and forth, at JVM level. One step back, current impl brings no harm to master nor good, but the new impl looks like may bring a new uncertainty. I incline to keep it still, and so, leave my -0.
