Subject [jira] [Commented] (YARN-7757) Refactor NodeLabelsProvider to be more generic and reusable for node attributes providers
Date Wed, 31 Jan 2018 12:16:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16346717#comment-16346717

Weiwei Yang commented on YARN-7757:
-----------------------------------

Hi [~sunilg]

Thanks, regarding to your comments
# It is fine to run script as NM user, that should be enough for most cases. Most of node
info should be readable by NM user and we'll explicitly doc out the runner of the script.
User will get that. But thanks for pointing this out.
# It makes sense, but since it's a trivial change I suggest we track it via part of our doc
task, I've noticed that in YARN-7865, please check.

Thanks

> Propose to do refactor on {{NodeLabelsProvider}}, {{AbstractNodeLabelsProvider}} to be
more generic, so node attributes providers can reuse these interface/abstract classes.
