             Summary: FS-CS converter: check deprecated increment properties for mem/vcores and fix DRF check
                 Key: YARN-10257
                 URL: https://issues.apache.org/jira/browse/YARN-10257
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Peter Bacsko
            Assignee: Peter Bacsko


Two issues have been discovered during fs2cs testing:

1. The value of two properties are not checked:

{{yarn.scheduler.increment-allocation-mb}}
{{yarn.scheduler.increment-allocation-vcores}}

Although these two are marked as deprecated, they're still in use and must be handled.

2. The following piece of code is incorrect - the default scheduling policy can be different fromDRF, which is a problem is DRF is used everywhere:

{code}
  private boolean isDrfUsed(FairScheduler fs) {
    FSQueue rootQueue = fs.getQueueManager().getRootQueue();
    AllocationConfiguration allocConf = fs.getAllocationConfiguration();

    String defaultPolicy = allocConf.getDefaultSchedulingPolicy().getName();

    if (DominantResourceFairnessPolicy.NAME.equals(defaultPolicy)) {
      return true;
    } else {
      return isDrfUsedOnQueueLevel(rootQueue);
    }
  }
{code}
