Subject [jira] [Commented] (YARN-2786) Create yarn cluster CLI to enable list node labels collection
Date Sat, 08 Nov 2014 04:23:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14203210#comment-14203210

Vinod Kumar Vavilapalli commented on YARN-2786:
-----------------------------------------------

bq. c) I realize neither of you were there when we ran HOD and dealt with Torque where a normal
course of action was to just delete the configuration and start it over because the label
configuration was completely unmanageable. I also recognize that my -1 on this "feature" is
falling on deaf ears and you're going to get this in come hell or high water. 
By the time I started on HOD, those experiments were presumably over, so I never heard about
them.

IAC, the crux of what you want is a per node script based configuration. That IS happening
as we speak as part of the tickets I referred to. Further, you don't want a central list of
valid labels which I disagree with. But sure, we will make this configurable to or not to
require a central list so that you can turn it off. Others like me can turn it on to avoid
random-labels-bubbling-up-in-my-cluster madness.

> With YARN-2778, we can list node labels on existing RM nodes. But it is not enough, we
should be able to: 
> 1) list node labels collection
> The command should start with "yarn cluster ...", in the future, we can add more functionality
to the "yarnClusterCLI"
