Github user JPercivall commented on the issue:
https://github.com/apache/nifi/pull/563
When attempting to view state for ConsumeKafka when Kafka is not running,
it does not handle it well. In the UI I see "An unexpected error has occurred
An error occurred communicating with the application core. Please check the
logs and fix any configuration issues before restarting."
In the logs I see the huge stack trace below that includes viewing and
clearing state (I never was able to click clear state though):
