bq. ZooKeeper connection in ZKRMStateStore never be closed.
Which version of Hadoop are you using? We are closing the ZK connection. See
ZKRMStateStore#closeInternal()
[~Tao Yang] Do you think this is still issue in latest version of hadoop?

> Recently RM full GC happened in one of our clusters, after investigating the
> dump memory and jstack, I found two places in RM may cause memory leaks after
> RM transitioned to standby:
> # Release cache cleanup timer in AbstractYarnScheduler never be canceled.
> # ZooKeeper connection in ZKRMStateStore never be closed.
> To solve those leaks, we should close the connection or cancel the timer when
> services are stopping.
