Zhijie Shen commented on YARN-3044:
-----------------------------------
bq. Well i had raised config related queries earlier as it dint get concluded
was planning to get it done as part of a new jira, AFAIK intention in ATS is to
collect the App side configs than server side ones. And RM will not be aware of
App configs, so my initial idea was to support additional interface in the
client to publish Application specific configs. Correct me if i am wrong and
also inform whether its ok to handle configs in another jira.
So can we undo the code change related to config for this jira?
bq. May be i did not get this clearly, but AFAIK the packages and classes for
the Timeline events & entities are different and the way we publish entities is
also different, so though the code looks duplicated i think nutting further to
be reduced/cleaned up here.
In general, I'm suggesting the code style in MAPREDUCE-6335, which seems to be
more clear. However, I'm okay to keep to the current code if it's complex to
refactor it.
bq. but you had commented to have single config
yarn.system-metrics-publisher.enabled and hence i had remodified.
Right, but it turns out to be that RM and NM seem not to be able to uniform the
configs (such as the new config added here) between them, and more than one
feature require somewhat version flag to differentiate the behavior. Never
mind. I'll take care of it separately.
