Varun Vasudev updated YARN-4172:
--------------------------------
Attachment: YARN-4172-YARN-3926.002.patch
bq. 1) Who will update DRC.resourceNames, I found currently it hardcoded to
memory and vcores.
This will be handled as part of later patches. For now, only memory and vcores
are supported. Eventually, the list will be generated via a config.
bq. 2) DominantResourceCalculator#compare: Need handle the case when
resourceName not existed at lhs or rhs?
This would throw an exception in getResourceInformation.
bq. Could use ResourceInformation.compareTo instead of
ResourceInformation.compareValue since resourceName equals to each other? Is it
still necessary to keep compareValue?
Good point. Fixed.
bq. 3) Suggest to use > = < to do compare since of switch (diff).
Fixed.
bq. 4) DRC#computeAvailableContainers need consider denominator == 0?
The current implementation doesn't handle the case - how should I handle it?
bq. 5) Is it possible we can return a dummy ResourceInformation (with value ==
0) instead of check exception at lots of places.
I would prefer to throw an exception - FairScheduler uses 0 Resource objects in
a lot of place - I don't want to return something that indicates the operation
was successful.
