Subject [jira] [Updated] (YARN-6927) Add support for individual resource types requests in MapReduce
Date Tue, 24 Oct 2017 17:08:01 GMT

Gergo Repas updated YARN-6927:
------------------------------
    Attachment: YARN-6927.004.patch

Thanks for the comments [~templedf].
1 - I think we have not discussed this before, but sounds good. I added this to YARN-6927.004.patch,
and made sure that only one of these resource names can be specified at once. I also renamed
cpu-vcores to vcores.
2 - Good point. I've been using ResourceUtils.getDefaultUnit() to fall back to the default
unit if the user did not provide one (this piece of code is in ResourceUtils.getRequestedResourcesFromConfig()),
but the getDefaultUnit() method returns no units for "memory" by default - I added some special
handling into TaskAttemptImpl and YARNRunner for this.

> YARN-6504 adds support for resource profiles in MapReduce jobs, but resource profiles
don't give users much flexibility in their resource requests.  To satisfy users' needs, MapReduce
should also allow users to specify arbitrary resource requests.
