--------------------------------------
Summary: NiFi does not stop timely when using
DistributedMapCacheClient and Server
Key: NIFI-11580
URL: https://issues.apache.org/jira/browse/NIFI-11580
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 1.21.0
Reporter: Michael W Moser
When using a DistributedMapCacheClientService and DistributedMapCacheServer,
and the DistributedMapCacheClientService has been enabled, then NiFi does not
stop within the graceful.shutdown.seconds period and has to be killed. It
would be nice to clean this up.
I setup a DistributedMapCacheClientService and DistributedMapCacheServer to
talk to each other, enabled both, then disabled
DistributedMapCacheClientService. I stopped NiFi and it was killed after 20
seconds instead of stopping in 2 or 3 seconds.
