             Summary: Simple UI Announcements Notification
                 Key: STORM-1860
                 URL: https://issues.apache.org/jira/browse/STORM-1860
             Project: Apache Storm
          Issue Type: Story
          Components: storm-core
    Affects Versions: 0.9.3
            Reporter: Derek Dagit


As a user of a storm cluster, I would like to be informed of current or 
scheduled maintenance on the cluster, so that I can plan my work & debug more 
efficiently.


This could be a really simple UI change.  The UI could look for a special file 
on the local disk. If found, it would display a notification near the top of 
the UI with the contents of this file.

It would be useful to announce an ongoing rolling upgrade of the cluster, 
scheduled future downtime, current known incidents, or other, even more general 
communications from administrators to users.
