Hi [~Naganarasimha], [~sunilg]

I am proposing we don't add such a central node attribute manager, instead like I commented in YARN-7031, can we just use the distributed manner? That is, let NM maintains node-attributes state (including persistent) and RM simply relies on the NM HB report. This is because for node attribute case, NM side discovery is required. So if centralized mode is used, that means we need to honor the attributes from NM HB, and at the same time we need to manage attributes set by admins. That makes RM code more complex. I think it is possible to add NM admin interface to update individual NM node attribute via CLI or REST, and expose this to RM admin service is also possible. So from end user view, there is no difference.

Please let me know your thoughts.

Thanks

> Similar to CommonNodeLabelsManager we need to have a centralized manager for Node Attributes too.
