Review comment:
We are re-creating the supporting actors without shutting them down. This
should result in memory leaks everytime the instance wins the leader election.
It is also not very nice that we occupy the main thread of the actor with
blocking IO.

> Mesos resource manager unable to connect to master after failover
> -----------------------------------------------------------------
>
> Key: FLINK-9936
> URL: https://issues.apache.org/jira/browse/FLINK-9936
> Project: Flink
> Issue Type: Bug
> Components: Mesos, Scheduler
> Affects Versions: 1.5.0, 1.5.1, 1.6.0
> Reporter: Renjie Liu
> Assignee: Gary Yao
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.5.3, 1.6.0
>
>
> When deployed in mesos session cluster mode, the connector monitor keeps
> reporting unable to connect to mesos after restart. In fact, scheduler driver
> already connected to mesos master, but when the connected message is lost.
> This is because leadership is not granted yet and fence id is not set, the
> rpc service ignores the connected message. So we should connect to mesos
> master after leadership is granted.
