Paul Grey commented on NIFI-11210:
----------------------------------
The `CacheClientRequestHandler.invoke()` method calls netty function
`awaitUninterruptibly()`, with no timeout. This should be updated to use the
timeout configured for the controller service. `CacheClientChannelInitializer`
should be updated to supply the configured timeout to the request initializer.

> If a client / server version handshake fails due to a network glitch, the
> DistributedMapCacheClientService can be left in a state where it stops
> processing new requests.
> Remediate by ensuring that network connection construction sets appropriate
> timeouts.
