Lukas Majercak updated HADOOP-15683:
------------------------------------
Description:
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.
> Client.setupConnection should not block Client.stop() calls
