Subject [jira] [Commented] (YARN-3390) Reuse TimelineCollectorManager for RM
Date Wed, 15 Apr 2015 03:51:59 GMT

Sangjin Lee commented on YARN-3390:
-----------------------------------

Thanks [~Naganarasimha] and [~zjshen]! I'll take a look at the patch a little more closely
later. I just wanted to bring to your attention YARN-3437. There I did a fairly similar (but
not identical) refactoring of TimelineCollectorManager as part of isolating the core piece
of the timeline collector manager independent of the NM-TS interaction, etc. So hopefully
we can arrive at a version that can satisfy both needs.

Also, a small nit: I'm not too sure if I like the name "NMTimelineCollectorManager" (the "NM"
part of it). It suggests bit too strongly that this is part of the NM. How about "NodeTimelineCollectorManager"
or another bit more independent name? I can't think of many other alternatives, so any suggestion
is welcome.
