Eric Payne created YARN-9894:
--------------------------------
Summary: CapacitySchedulerPerf test for measuring hundreds of apps
in a large number of queues.
Key: YARN-9894
URL: https://issues.apache.org/jira/browse/YARN-9894
Project: Hadoop YARN
Issue Type: Improvement
Components: capacity scheduler, test
Affects Versions: 3.1.3, 3.2.1, 2.8.5, 2.9.2
Reporter: Eric Payne
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
