[jira] [Commented] (YARN-4335) Allow ResourceRequests to specify ExecutionType of a request ask

    [ https://issues.apache.org/jira/browse/YARN-4335?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15082917#comment-15082917 ] 

Konstantinos Karanasos commented on YARN-4335:
----------------------------------------------

Thank you for the feedback, [~leftnoteasy].

I addressed your first two comments and will now upload a new version of the patch.

bq. Javadocs of ExecutionType: if we use ExecutionType for resource request, I would suggest to add description that scheduler could use it to decide if idle resources could be used by the resource request.
Just double-checking: do you mean adding an additional description in the javadoc of the ExecutionType?
Let me know and I will go ahead and update the patch.

> YARN-2882 introduced container types that are internal (not user-facing) and are used by the ContainerManager during execution at the NM.
> With this JIRA we are introducing (user-facing) resource request types that are used by the AM to specify the type of the ResourceRequest.
> We will initially support two resource request types: CONSERVATIVE and OPTIMISTIC.
> CONSERVATIVE resource requests will be handed internally to containers of GUARANTEED type, whereas OPTIMISTIC resource requests will be handed to QUEUEABLE containers.
