Yufei Gu commented on YARN-6971:
--------------------------------
Thanks [~sunilg] for the details. I can't think about more to share.
In that sense, we are not only replace unnecessary
{{BuilderUtils.newResource()}}, but also need to change its name to something
like {{createResourceForRPC()}} or at least document when to use
{{BuilderUtils.newResource()}} and when to use others.
Do you think this jira should be a subtask of YARN-3926? I assume there is no
duplicate one.
> Clean up different ways to create resources

> Key: YARN-6971
> URL: https://issues.apache.org/jira/browse/YARN-6971
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager, scheduler
> Reporter: Yufei Gu
> Priority: Minor
> Labels: newbie
>
> There are several ways to create a {{resource}} object, e.g.,
> BuilderUtils.newResource() and Resources.createResource(). These methods not
> only cause confusing but also performance issues, for example
> BuilderUtils.newResource() is significant slow than
> Resources.createResource().
> We could merge them some how, and replace most BuilderUtils.newResource()
> with Resources.createResource().
