Mark Bean created NIFI-3731:
-------------------------------
Summary: Excessive Curator messages
Key: NIFI-3731
URL: https://issues.apache.org/jira/browse/NIFI-3731
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.1.1
Reporter: Mark Bean
Priority: Minor
Occasionally, while testing scenarios on a 3-Node cluster a Node will be
removed from the cluster. Sometimes, the log files begin filling with an
inordinate amount of repeated messages from the Curator. I'm still trying to
track down what instigates this, but most likely it is when one of the 3 ZK
servers becomes unavailable. Is there a way to suppress or reduce the frequency
of the following messages? Currently, it is repeated more than once/millisecond.
