> When leader failover happens (either automatically or manually), tez sessions
> are closed. But client connections are not. We need to close the client
> connections explicitly so that workload manager revokes all the guaranteed
> slots and upon reconnection client will connect to active HS2 instance (this
> is to avoid clients reusing the same connection and submitting queries to
> passive HS2). In future, some timeout or other policies (may be WM will run
> everything speculatively) can be added.
