Wangda Tan commented on YARN-2495: ---------------------------------- For your questions: 1. It's not first priority, let's just keep it here and move on with the script one 2. That's make sense, and could you take a look at the health check script, is it as same as you mentioned? (I guess so) 3. I can remember that :), make sense to me. If there's any merge needed, we can tackle it in a separated JIRA. 4. I just marked to 2.8, since 2.7 is planned to be released within 2 weeks, I think it will be hard to fit in that timeframe. IIRC, this JIRA contains a abstract node label provider only. I suggest don't add more options for configuring node label provider for now (saying, set provider=script-based-provider), to avoid potentially unnecessary switches. For now, as we discussed, you can leave an empty provider implementation (but need proper impl to do tests), script-based-provider can be addressed separately. > Allow admin specify labels from each NM (Distributed configuration) > ------------------------------------------------------------------- > > Key: YARN-2495 > URL: https://issues.apache.org/jira/browse/YARN-2495 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Reporter: Wangda Tan > Assignee: Naganarasimha G R > Attachments: YARN-2495.20141023-1.patch, YARN-2495.20141024-1.patch, > YARN-2495.20141030-1.patch, YARN-2495.20141031-1.patch, > YARN-2495.20141119-1.patch, YARN-2495.20141126-1.patch, > YARN-2495.20141204-1.patch, YARN-2495.20141208-1.patch, > YARN-2495_20141022.1.patch > > > Target of this JIRA is to allow admin specify labels in each NM, this covers > - User can set labels in each NM (by setting yarn-site.xml (YARN-2923) or > using script suggested by [~aw] (YARN-2729) ) > - NM will send labels to RM via ResourceTracker API > - RM will set labels in NodeLabelManager when NM register/update labels -- This message was sent by Atlassian JIRA (v6.3.4#6332)
