-----------------------------------------

Hi [~varun_saxena], 
Thanks for working on this issue, overall i feel the patch is fine but just requires rebase
based on changes of YARN-4356.

Also one basic question related to the structure of *TimelineEntity* (Sorry for putting this
across now!), will there be any advantage of {{modified time}} ? If not used as part of any
query then better to avoid storing it as in some entities it will be a disadvantage, for example
in case of {{ContainerEntity}} we are updating the modified time for each container usage
report, unnecessary updates will happen in the backend, Correct me if i my understanding is
wrong.

Also would like to take shot in committing this patch once the rebase is done, if no one has
concerns !

> While publishing entities from RM and elsewhere we are not sending created time. For
instance, created time in TimelineServiceV2Publisher class and for other entities in other
such similar classes is not updated. We can easily update created time when sending application
created event. Likewise for modification time on every write.
