Sangjin Lee commented on YARN-5699:

I'd like to know what would be made much easier with having the created time as 
entity info that is inconvenient or difficult with the explicit created time 
attribute. I get that it would be more symmetric with the finished time, but 
that alone is not a *strong* argument for replicating this info.

Since we're talking about container entities, this is probably the most number 
of entities in the storage. If we can help not add a column *per object* 
unnecessarily, I think it would be a good thing.

> Currently, all the container information are published at 2 places. Some of 
> them are at entity info(top-level) and some are  at event info. 
> For containers, some of the event info should be published at container info 
> level. For example : container exist status, container state, createdTime, 
> finished time. These are general information to container required for 
> container-report. So it is better to publish at top level info field.
