Description

YARN-10552 introduced changes that is resulting in a StackOverflowError.
1. org.apache.hadoop.yarn.sls.scheduler.SLSCapacityScheduler#handle calls org.apache.hadoop.yarn.sls.scheduler.SLSSchedulerCommons#handle

2. org.apache.hadoop.yarn.sls.scheduler.SLSSchedulerCommons#handle calls scheduler.handle again. The original code called super.handle()

Note: I don't have an idea why the UT tests passed for YARN-10552.
