Varun Vasudev updated YARN-3348:
--------------------------------
Attachment: apache-yarn-3348.3.patch
bq. In YarnClusterMetricsPBImpl, should the default num*NodeManagers return 0 ?
Fixed.
bq. getApplications in YarnClient.java may be an abstract method?
It's a public class. Adding an abstract method will break compatibility.
bq. “Queue Applications:” - if it’s aggregated number , maybe Queue(s) ?
Fixed.
Some other changes:
# Based on an offline conversation with Jian, I've moved the app reports cache
into TopCLI itself for now.
# Improved help
# The queue memory statistics are in GB instead of MB.
> Add a 'yarn top' tool to help understand cluster usage

> 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.
