Wangda Tan commented on YARN-4484:
----------------------------------
Thanks [~sunilg]/[~bibinchundatt],
bq. In new patch we can also take care of condition where the label mapping is
not available in queue.
Sorry I may not get this, could you elaborate?
Few comments for the patch:
- Instead of using componentwiseMax, {{available-headroom-per-partition =
partition-used >= partition-configured ? componentwiseMax(partition-configured
- partition-used, 0) : 0}}. This is because when partition-used >=
partition-configured, you cannot allocate anything so the available should be
considered to 0.
- It's better to add a test.
> Available Resource calculation for a queue is not correct when used with
> labels
