Subject [jira] [Commented] (YARN-238) ClientRMProtocol needs to allow the specification of a ResourceRequest so that the Application Master's Container can be placed on the specified host
Date Thu, 22 Nov 2012 18:55:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13502897#comment-13502897
] 

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)?

> 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.
