Description

I was looking at https://builds.apache.org/job/PreCommit-YARN-Build/2165//testReport/org.apache.hadoop.yarn.sls/TestSLSRunner/testSimulatorRunning/
I am able to reproduce the failure locally.

I found that FairSchedulerConfiguration.getAllocationFile() doesn't read the yarn.scheduler.fair.allocation.file config entry from fair-scheduler.xml

This leads to the following:

Caused by: org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.AllocationConfigurationException: Bad fair scheduler config file: top-level element not <allocations>
