[jira] [Commented] (NIFI-11210) Missing network read timeout in DistributedMapCacheClientService

["Paul Grey (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-11210?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17692261#comment-17692261 ] 

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.
