Subject [jira] [Commented] (YARN-5587) Add support for resource profiles
Date Tue, 25 Oct 2016 23:03:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5587?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15606739#comment-15606739

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

I feel we should try to keep this simple. Given that we have already introduced a {{ProfileCapability}}
class that takes a profile name and a possible Capability override, I propose:
# We create a special {{ProfileCapability}} with profile name *NONE* where user only specifies
the capability (Resource). This would be equivalent to our old {{Resource}}
# We replace the capability(Resource) argument in both the {{ContainerRequest}} and {{ResourceRequest}}
with {{ProfileCapability}}. Maybe for backward compatibility, we have 1 constructor that takes
Resource and 1 that takes ProfileCapability. We then convert a Resource to ProfileCapability(NONE,
Resource) in the AMRMClient.
# In the rest of the {{AMRMClient}} codebase, including the {{RemoteRequestsTable} }we just
use {{ProfileCapability}}
