-----------------------------------
I'll try and track down the exact scenario that causes this but it's happen to me several times and some other folks on Slack.

> Key: NIFI-7035
> URL: https://issues.apache.org/jira/browse/NIFI-7035
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Shawn Weeks
> Priority: Trivial
>
> 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.
