Varun Vasudev updated YARN-4285:
--------------------------------
Attachment: YARN-4285.003.patch
bq. 1) Since ApplicationResourceUsageReport is public API, I suggest to rename
parameter, getter/setter name from Perc to Percentage. Same as
yarn_protos.proto.
Fixed.
{quote}
2)
if (rmContext.getScheduler() instanceof YarnScheduler) {
calc = rmContext.getScheduler().getResourceCalculator();
}
rmContext.getScheduler() should be always YarnScheduler, correct? This check
maybe not required.
{quote}
Good catch! Fixed.
bq. 3) Is it better to change int percentage to float, for AppInfo and other
APIs.
Fixed.
bq. 4) Since this is not a trivial patch, could you add some tests to verify if
SchedulerApplicationAttempt can return percentage properly?
Fixed.

> It would be useful to display the resources consumed as a %of the queue and
> the cluster to identify apps that are using a lot of resources.
