Hi @manishg ,

Only the top processor in a given flow can be set to execute on "Primary Node". No downstream processor can be set as such. If you want downstream processors to execute on a single node , then open the Queue configuration going to the FetchXMLFile , Under Settings tab , select "Single node" from the Load Balance Strategy" drop down. However selecting this option there is no guarantees which node is it going to be as the manual indicates:

"

Single node: All FlowFiles will be sent to a single node in the cluster. Which node they are sent to is not configurable. If the node is disconnected from the cluster or if unable to communicate with the node, the data that is queued for that node will remain queued until the node is available again.

"

If that helps please accept solution.

Thanks
