Subject [jira] [Commented] (YARN-2786) Create yarn cluster CLI to enable list node labels collection
Date Tue, 04 Nov 2014 22:18:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-2786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14196953#comment-14196953

Vinod Kumar Vavilapalli commented on YARN-2786:

I see the discussion on YARN-796, YARN-2495.

Both the implementations are going to be done soon, so we can agree to disagree on having
both a decentralized way and a central way to assign labels against nodes.

bq. "Where did this label come from? I guess someone manually added it via the shell at some
This is simply audit/lineage. As part of YARN-2495, we can make sure an admin can only configure
it using only one of the mechanisms and not both. I doubt if this is necessary, but sure.

bq. This is actually supporting my claim that adding cluster for this purpose is a bad idea,

Don't follow. We need a "yarn cluster" for ton of other things that we don't have today.

I can already list a few
yarn cluster --list-nodes
yarn cluster --list-nodes --status=UNHEALTHY
yarn cluster --list-racks
yarn cluster --current-resource-usage

> 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"
