[jira] [Commented] (YARN-2033) Investigate merging generic-history into the Timeline Store

    [ https://issues.apache.org/jira/browse/YARN-2033?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13995438#comment-13995438 ] 

Karthik Kambatla commented on YARN-2033:
----------------------------------------

Thanks Vinod. Would like to hear your thoughts on the following:
What are the perceived scalability requirements of the history store and timeline store? I would think the timeline store might have to supporting storing a lot more information than the history store. In that case, one might want to keep them separate?

> Having two different stores isn't amicable to generic insights on what's happening with applications. This is to investigate porting generic-history into the Timeline Store.
> One goal is to try and retain most of the client side interfaces as close to what we have today.
