Hari Sekhon commented on YARN-3670:
-----------------------------------
I understand (you can't imagine how often I've had to refrain from asking for
Maps and Reduces to be available in UI like trusty old MRv1). At the moment
it's too opaque, which is a first generation side-effect of Yarn being a
generally abstracting resource manager.
However, perhaps it would be possible to create a generic mechanism that allows
jobs to publish key-value pairs which could be populated with either settings
or counters to be displayed via a new named link also specified per set of
key-value pairs, such as a job could publish "counters" or "configuration". In
this way both the MapReduce client, the Tez client and any other YARN apps
would have the ability to publish any arbitrary key-value pair table of
information to YARN to display in the UI?
This would help immensely with debugging yarn jobs.
