             Summary: Don't spam logs with Apache Curator errors on Zookeeper Disconnect
                 Key: NIFI-7035
                 URL: https://issues.apache.org/jira/browse/NIFI-7035
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Shawn Weeks


Sometimes when you startup NiFi and not all of the Zookeeper nodes aren't up it fills the logs with Apache Curator errors like this one. We should be able to improve this a bit as logging the same error repeatedly isn't helpful.
