-------------------------------
Summary: Add ability to "empty queue" on an entire process group
Key: NIFI-5329
URL: https://issues.apache.org/jira/browse/NIFI-5329
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Affects Versions: 1.6.0
Reporter: Mark Bean
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"
