             Summary: List File isn't stopped when migrated from Single node to Clustered NiFi setup
                 Key: NIFI-7382
                 URL: https://issues.apache.org/jira/browse/NIFI-7382
             Project: Apache NiFi
          Issue Type: Bug
          Components: Configuration, Configuration Management
    Affects Versions: 1.9.2
         Environment: On windows, Linux. Not tried in mac
            Reporter: Ghanashyam
         Attachments: NiFi-ListFile-issue.JPG, NiFi-cluster-issue.JPG, NiFi-exceptionState-issue.JPG

NiFi was 1st deployed in single node (node06) and a flow was created like shown below 

ListFile --> FetchFile --> UpdateAttribute --> PutHDFS -->..

The flow works well in single node and was versioned using nifi registry. Once registered, NiFi was scaled Up with 2 more nodes (node04 & node05) to form a cluster of 3 nodes. The same version of the flow from the nifi registry was copied on both of the new nodes. 

Issue:

The primary is still the original node and the new nodes are acting like secondary. The new nodes however does not have the directory structure which the ListFile processor used to list the files, hence there is an exception state in the processor. 

If I wish to change the scheduling state from all nodes to primary  nodes it is not allowing this operation. It is not allowing any modifications in this state of the processor.  The error is pops up says the processor is not stopped and is unable to fulfill the request. This is mis leading and has to be corrected with proper statements.
