>             Project: Hadoop Common
>          Issue Type: Improvement

>            Reporter: Lukas Majercak

>
> If the IPC Client is still setting up connections when Client.stop() is called, the stop()
call will not succeed until setupConnection finishes (successfully or with failure). 
> This can cause very long delay (maxFailures * timeout can be more than 10minutes depending
on configuration) in stopping the client. 
> Client.stop() is for example used in NN switch from Standby to Active, and can therefore
have very bad consequences and cause downtime.
