Sangjin Lee commented on YARN-2928:
-----------------------------------
I agree with the aggregated log viewer being part of ATS. Probably not for the
first phase, but eventually. I'll update the doc accordingly.
Speaking of which, I think we may want to standardize the names of the
components, especially the one we launch to write data. We've used several
names to refer to the same thing, and it'd be good if we just settle on one
name so there is no confusion. May sound like a small thing, but it'd help
discussing things rapidly.
We used: "ATS writer", "ATS writer companion", "aggregator", and "ALA". I'm not
married to any names here. How about "Timeline aggregator"? I'm open to
suggestions.
