>          Components: balancer & mover
>    Affects Versions: 2.6.0
>            Reporter: Akira AJISAKA

> When balancer completes rebalance and exits, it does not delete its pid file. Starting
balancer again, then "kill -0 pid" to confirm the balancer process is not running.
> The problem is: If another process is running as the same pid as `cat pidfile`, balancer
fails to start with following message:
> {code}
>   balancer is running as process 3443. Stop it first.
> {code}
