Subject [jira] [Commented] (YARN-314) Schedulers should allow resource requests of different sizes at the same priority and location
Date Wed, 20 May 2015 18:10:01 GMT

Wangda Tan commented on YARN-314:
---------------------------------

[~kasha],
Actually I'm not quite sure about this proposal, what's the benefit of putting all apps' requests
together comparing to hold one data structure per app, is there any use case?

> Currently, resource requests for the same container and locality are expected to all
be the same size.
> While it it doesn't look like it's needed for apps currently, and can be circumvented
by specifying different priorities if absolutely necessary, it seems to me that the ability
to request containers with different resource requirements at the same priority level should
be there for the future and for completeness sake.
