> When HSI component is started, it destroys the llap app and then starts it. However,
if multiple HSI instances are deployed then when an instance is started (due to fail over
of another instance) then it should be checked if llap is running and if it is then it should
not be restarted.
> Multiple HSI instances are deployed only in an active-passive scenario to enable fail
over. As llap app is an YARN app, it automatically supports failover. So not forcing a restart
of llap is a requirement when HSI is deployed in an active-passive mode.
