Vrushali C commented on YARN-4238:
----------------------------------
[~gtCarrera9] ,
[~varun_saxena] mentioned that he most probably recollects that the modified
time was being used to query the in memory store in ats v1. Do you have any
idea if that was for Tez? Do you know if Tez specifically needs entities back
in some chronological order? Do you think we should email them and check?
If that is the case, we do need the modification time class member. Then we
perhaps can go ahead with updating it in each setter function in the
TimelineEntity class.
> createdTime and modifiedTime is not reported while publishing entities to
> ATSv2

> 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.
