Naganarasimha G R commented on MAPREDUCE-6424:
----------------------------------------------
bq. If we don't do this, then we need to find a way to transfer metrics from
certain framework-specific entities to the application entities so that they
can be aggregated. I would think that would be considerably more involved.
Agree, i was thinking of linking this jira to YARN-3401 and comment there to
provide alternate approach to publish app metrics (& configuration as part of
YARN-3401) from app and currrently applications are publishing System entities
directlty.
bq. As you mentioned, we can carry on the discussion in a new JIRA.
Ok
Have uploaded the patch with fixes for you suggestion [~sjlee0].
