Reidddddd commented on issue #468: HBASE-22822 : Un/Re-schedule balancer chore with balance_switch URL: https://github.com/apache/hbase/pull/468#issuecomment-520361140 > Hence, balancer will be turned off before starting with rolling restart and turned on after all n servers are restarted (not in-between restarts of individual servers). Hmm, right. But it only works for master and branch-2. But even it only targets to a single RS where balance off is only a temporary move, do you really think it is a good practice or worthy of destructing then constructing a task, just within few minutes? > However, I am just wondering if there are any other such scenarios where we keep turning on/off balancer quite frequently as part of some workflow? Just rolling restart, maybe. One place I'm not sure is RSGroup's move_regions op.
