Benjamin Teke updated YARN-10565:
---------------------------------
    Description: 
In YARN-10504 weight mode support was introduced to CS. This jira is a followup 
to simplify and restructure the initialization, so that the weight 
calculation/absolute/percentage mode is easier to understand and modify.

To be refactored:
* In ParentQueue.java#1099 the error message should be more specific, instead 
of the {{LOG.error("Fatal issue found: e", e);}}
*- AutoCreatedLeafQueue.clearConfigurableFields should clear NORMALIZED_WEIGHT 
just to be on the safe side-
*- Uncomment the commented assertions in 
TestCapacitySchedulerAutoCreatedQueueBase.validateEffectiveMinResource-
*- Check whether the assertion modification in TestRMWebServices is absolutely 
necessary or could be hiding a bug.-
* -Same for TestRMWebServicesForCSWithPartitions.java-

Additional information:
The original flow was modified to allow the dynamic weight-capacity 
calculation. 
This resulted in a new flow, which is now harder to understand.
With a cleanup it could be made simpler, the duplicate calculations could be 
avoided. 
The changed functionality should either be explained (if deemed correct) or 
fixed (see YARN-10590).
Investigate how the CS reinit works, it could contain some possibly redundant 
initialization code fragments.

Note: Since most of the items were completed in other refactor items, only the 
first one is being patched here.
