Subject [jira] [Commented] (YARN-2729) Support script based NodeLabelsProvider Interface in Distributed Node Label Configuration Setup

Vinod Kumar Vavilapalli commented on YARN-2729:
-----------------------------------------------

bq. I think the format expected from the command should be more structured. Specifically as
we expect more per-label attributes in line with YARN-3565.
bq. So IMHO if there is plan to make this interface public & stable then would be better
do these changes now itself if not it would better done after requirement for constraint labels,
so that more clarity on structure would be there? Tan, Wangda and you can share your opinion
on this, based on it will do the modifications.
I think once we start marking this script-based provider feature as public, the expected output
from the script will automatically become a public interface unless we explicitly say no.
We should start thinking about this now to avoid uncertainty in the future?

bq. These needs to be done irrespective of the label provider (system or user's) hence kept
it in NodeStatusUpdaterImpl , but if req to be moved out then we need to bring in some intermediate
manager(/helper/delegator) class between NodeStatusUpdaterImpl and NodeLabelsProvider.
Isn't AbstractNodeLabelsProvider a good place to do these steps?
