> Key: NIFI-4747
> URL: https://issues.apache.org/jira/browse/NIFI-4747
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.2.0, 1.4.0

> We schedule a getHDFS Processor CRON driven at "0 0 15 * * ?" so that it
> should run at 15:00:00 every day. If we start the processor it gives an error
> message even before CRON should have triggered the Processor as shown below.
> The question is why that is happening and how can it be fixed?
