Summary: Implement UI support for draining a Process Group
Key: NIFI-16576
URL: https://issues.apache.org/jira/browse/NIFI-16576
Project: Apache NiFi
Issue Type: New Feature
Components: Core UI
Reporter: Mark Payne
Assignee: Mark Payne
Add a Drain action to the Process Group context menu, as described in
[NIP-51|https://issues.apache.org/jira/browse/NIP-51].
Choosing Drain opens a dialog that shows a progress bar for the drain and a
button to cancel it. The dialog also lists the components that keep the drain
from finishing. Hovering over a component's warning icon shows why it is
blocking, and once the drain has stopped, the user can go to that component.
