Subject [jira] [Commented] (YARN-5085) Add support for change of container ExecutionType
Date Thu, 08 Dec 2016 16:34:58 GMT

Subru Krishnan commented on YARN-5085:
--------------------------------------

Thanks [~asuresh] for initiating this discussion. I'll take a detailed look when I am back.
One high level question - shouldn't we be using the *UpdateResourceRequest* API introduced
in YARN-5221 to achieve this as IIRC that was primary motivation behind it?

> YARN-2882 introduced the concept of {{ExecutionType}} for containers and it also introduced
the concept of OPPORTUNISTIC ExecutionType.
> YARN-4335 introduced changes to the ResourceRequest so that AMs may request that the
Container allocated against the ResourceRequest is of a particular {{ExecutionType}}.
> This JIRA proposes to provide support for the AM to change the ExecutionType of a previously
requested Container.
