Zhe Zhang commented on YARN-2694:
---------------------------------
Hi [~jianhe], [~leftnoteasy], I have a few questions about this change:
bq. Currently, node label expression supporting in capacity scheduler is
partial completed. Now node label expression specified in Resource Request will
only respected when it specified at ANY level.
Could you elaborate a bit on this? Is it because it's hard to satisfy both node
label and locality requirements? If so, when do you think we will be ready to
enable Node or Rack level resource requests?
Thanks,
