Subject [jira] [Commented] (YARN-4238) createdTime and modifiedTime is not reported while publishing entities to ATSv2
Date Wed, 06 Jan 2016 23:19:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-4238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15086476#comment-15086476
] 

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.

> 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.
