Tom White commented on MAPREDUCE-2638: -------------------------------------- Thanks Matei. The preemption intervals are indeed very low - they are set like this in order to trigger preemption in a pseudo-distributed cluster and so stress the scheduler. For larger clusters the settings you suggest are entirely appropriate, as well as increasing the sleep time in the jobs by setting {{test.fairscheduler.sleepTime}} to a higher value. > Create a simple stress test for the fair scheduler > -------------------------------------------------- > > Key: MAPREDUCE-2638 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-2638 > Project: Hadoop Map/Reduce > Issue Type: Test > Components: contrib/fair-share > Reporter: Tom White > Assignee: Tom White > Attachments: MAPREDUCE-2638.patch, MAPREDUCE-2638.patch > > > This would be a test that runs against a cluster, typically with settings > that allow preemption to be exercised. -- This message is automatically generated by JIRA.
