Subject [jira] [Commented] (YARN-7871) Node attributes reporting from NM to RM
Date Wed, 07 Feb 2018 09:28:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16355204#comment-16355204

Sunil G commented on YARN-7871:

Thanks [~cheersyang]

Some comments in general:
 # With this patch, NM could be configured either for CONFIG_NODE_DESCRIPTOR_PROVIDER or SCRIPT_NODE_DESCRIPTOR_PROVIDER?
It could be possible that there are some static configs for any node and some additional attributes
could be later added from scripts?
 # In {{createNodeAttributesProvider}} i am not very clear about the default case handling.
We could through an error when config/scripts is not given correct?
 # Is RMNodeAttributesManager need to part of this jira? Because i think that manager needs
to handle all 3 types of attributes, so I am not very sure whether this is now a placeholder
or not? Could you please confirm
