Eric Payne commented on YARN-9894:
----------------------------------
Thanks a lot, [~jhung] for your review comments. Sorry for the long delay.
{quote}can we change this to: Integer.getInteger("NumberOfQueues", 40);, etc.?
{quote}
Done. Good suggestion.
{quote}it seems there's quite a bit of duplicate code, any chance we can
refactor it?
{quote}
I combined the driver method
{{testUserLimitThroughputWithNumberOfResourceTypes}} with the code that I had
originally put into the new test {{testUserLimitThroughputWithManyQueues}}

Also, since these are performance tests, when run together they can take a
long time (for me ~20 minutes). They kept hitting the surefire.fork.timeout:
{panel:title=hadoop-project/pom.xml}
<surefire.fork.timeout>900</surefire.fork.timeout>
{panel}
So, I added the following switch to the command line in order to get all the
way through all of the test cases:
{noformat}
-Dsurefire.fork.timeout=1800
{noformat}

> Project: Hadoop YARN
> Issue Type: Improvement
> Components: capacity scheduler, test
> Affects Versions: 2.9.2, 2.8.5, 3.2.1, 3.1.3
> Reporter: Eric Payne
> Assignee: Eric Payne
> Priority: Major
> Attachments: YARN-9894.001.patch, YARN-9894.002.patch

>
> I have developed a unit test based on the existing TestCapacitySchedulerPerf
> tests that will measure the performance of a configurable number of apps in a
> configurable number of queues. It will also test the performance of a cluster
> that has many queues but only a portion of them are active.
> {code:title=For example:}
> $ mvn test
> -Dtest=TestCapacitySchedulerPerf#testUserLimitThroughputWithManyQueues \
> -DRunCapacitySchedulerPerfTests=true
> -DNumberOfQueues=100 \
> -DNumberOfApplications=200 \
> -DPercentActiveQueues=100
> {code}
> - Parameters:
> -- RunCapacitySchedulerPerfTests=true:
> Needed in order to trigger the test
> -- NumberOfQueues
> Configurable number of queues
> -- NumberOfApplications
> Total number of apps to run in the whole cluster, distributed evenly across
> all queues
> -- PercentActiveQueues
> Percentage of the queues that contain active applications
