Varun Vasudev commented on YARN-4081:
-------------------------------------
Thanks for the feedback Srikanth!
bq. why use a Map. Is there a rough idea how many different resources one may
want to encode?
I would like the resource types supported to be configured and not set in code.
There's a proposal attached in the parent JIRA that goes into more detail on
this. We've seen tickets filed on YARN for adding disk, network, and HDFS
bandwidth as resource types. I would prefer it if we can let users just
configure the types they want to use and allow them to add arbitrary resource
types for scheduling(for example schedule based on the number of licenses
available on a node). Is there an alternate structure you would prefer for me
to use?
bq. Ditto for encapsulating strings in URIs
In the proposal, I propose using URIs as the identifier for the resource
type(similar to what Kubernetes uses).
bq. ResourceInformation wrapper over doubles
I'm didn't understand this - are you asking why we're using ResourceInformation
instead of using doubles?
