Subject [jira] [Commented] (YARN-5587) Add support for resource profiles
Date Tue, 25 Oct 2016 23:11:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5587?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15606760#comment-15606760
] 

Arun Suresh commented on YARN-5587:
-----------------------------------

Hmmm... Actually, I think we have to deal with one other issue in the {{AMRMClient}}:
Once a Container is returned by the RM, the AMRMClient uses the {{getMatchingRequests()}}
api to retrieve matching ContainerRequests and remove it.

This implies that we need to have an equivalence relationship from a *Resource* to a *ProfileCapability*,
else the matching won't work. Thus I think we might have to normalize all "named" ProfileCapabilities
to a either a Resource or a NONE ProfileCapability (with the override being the complete resource)

Either that, or we have to ensure that these new requests are tagged with unique 'allocationRequestIds',
for which we already have a separate {{getMatchingRequests}} that matches ContainerRequests
to Containers only based on the allocationRequestId.
