    Description

      • The following 2 test cases are failing on unrelated patches very often:

      hadoop.yarn.server.resourcemanager.scheduler.fair.TestFairScheduler

      hadoop.yarn.server.resourcemanager.scheduler.fair.TestFairSchedulerPreemption

      Here is an example of both failures
