Description

It is desirable to clear all queues in a section of the flow. Specifically, a Process Group can be taken as the unit to which 'empty queue' would be applied. All connections within the Process Group are emptied.

If the user does not have permission to empty a given queue, it should be excluded. However, all connections which the user has permission should complete successfully. A dialog at the end of the operation should indicate "X FlowFiles (Y bytes) were removed from Z queues". If appropriate, the dialog should also include "X queues were not emptied due to insufficient permission"
