--------------------------------------------------------------

[~till.rohrmann]  Void ? I see. I would think {code}@GuardedBy("lock){code} 
might a wrong as well. Could we do a refine like the following ?

Change the code 
{code}
@GuardedBy("lock")
        private ResourceManager resourceManager;
{code}

to 
{code}
private volatile ResourceManager resourceManager;
{code}
[~Zentol] FYI. Thanks and appreciate it.

> In YarnFlinkApplicationMasterRunner#runApplicationMaster() :
> {code}
>       synchronized (lock) {
>         LOG.info("Starting High Availability Services");
> ...
>       }
>       // wait for resource manager to finish
>       resourceManager.getTerminationFuture().get();
> {code}
> resourceManager#getTerminationFuture() is called without holding lock.
> We should store the value returned from 
> resourceManager#getTerminationFuture() inside the synchronized block.
