> 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.
