Naganarasimha G R updated YARN-3044:
------------------------------------
Attachment: YARN-3044.20150406-1.patch
On after thoughts, i have changed changed the approach for this jira (similar
to the one mentioned by Zhijie ), because creating seperate stack was not only
inducing too many changes but i was also skeptical that in future supporting
removal of dependency from timelineservice project in RM project will again
induce changes in seperate stack for V2 approach.
So approach what i have taken is
1> SMP will exist and SMP creates RMTimelineCollector. and RM will not be aware
of RMTimelineCollector.
2> Seggregrate the V1 event handler code from SMP as TimelineV1Handler .
(simpler to remove V1 support it in future )
3> add modifications in SMP such that TimelineV1Handler or RMTimelineCollector
(V2) will be created based on configuration. Also appropriate Dispatchers are
to be selected.
I have also incorporated the changes to support RMContainer metrics based on
configuration (Junping's comments).
Pending tasks :
* Testcases for RMTimelinecollector is not completed, as i dint want to take
the approach of TestDistributedShell as tests in it are mostly checking
whether the required files are created but in case of TestRMTimelinecollector,
we need to check whether the Entities are properly populated, which requires
Reader API and it seems to be not finalized yet. Also even to make use
FileSystemTimelineWriterImpl to test requires TimelineCollectorContext and
hence the dependency on YARN-3390
* As mentioned earlier AppConfig information is not completely available in RM
side, hence currently have populated the Environment config available in RMApp.
Shall i raise a new jira to support a method in TimelineClient interface to
load Appconfig ?
