Sandy Ryza commented on YARN-801:
---------------------------------
As YARN is agnostic to what its containers are used for, the RM won't have any
information about what tasks are running inside them. This could possibly be
added to the AM REST APIs, if it's not already there.
> Expose container locations and capabilities in the RM REST APIs

> It would be useful to be able to query container allocation info via the RM
> REST APIs. We should be able to query per application, and for each
> container we should provide (at least):
> * location
