Varun Vasudev updated YARN-3348:
--------------------------------
Attachment: apache-yarn-3348.0.patch
Uploaded initial version of the patch. Most of the work is in a new TopCLI
class. I added an application reports cache in ClientRMService with a timeout
of 5 seconds as well as a boolean in GetApplicationsRequest to fetch cached
versions of the reports.
The tool essentially prints out the application report. The default refresh
rate is 3 seconds.

> It would be helpful to have a 'yarn top' tool that would allow administrators
> to understand which apps are consuming resources.
> Ideally the tool would allow you to filter by queue, user, maybe labels, etc
> and show you statistics on container allocation across the cluster to find
> out which apps are consuming the most resources on the cluster.
