> Project: HBase
> Issue Type: Improvement
> Components: Balancer, master
> Affects Versions: 3.0.0, 1.5.0, 2.2.1
> Reporter: Viraj Jasani

> Priority: Major
> Fix For: 3.0.0, 1.5.0, 2.2.2

>
> balance_switch turns on/off balancer. When it is turned off, we don't remove
> balancer chore from scheduled chores hence it keeps running only to
> eventually find out that it is not supposed to perform any action(if balancer
> was turned off). We can unschedule the chore to prevent the chore() execution
> and reschedule it when it is turned on by balance_switch.
> This should also facilitate running balancer immediately after triggering
> balance_switch true, and then chore would continue running as per duration
> provided in hbase.balancer.period.
