Harsh J commented on YARN-238:
------------------------------
Is there also need for this to be a "strict" need or is it good to be flexible
(i.e. non guaranteeing) like other resource requests (we do a good locality job
to not have this concern very frequently, but still)?
> ClientRMProtocol needs to allow the specification of a ResourceRequest so
> that the Application Master's Container can be placed on the specified host

> Currently a client is able to specify only resource requirements in terms of
> amount of memory required while launching an ApplicationMaster. There needs
> to be a way to ask for resources using a ResourceRequest so that a host name
> could be specified in addition to the amount of memory required.
