Hemanth Yamijala commented on ATLAS-512:
----------------------------------------

Yes it does. In either case, hooks should ideally not have a dependency on 
Atlas client.

> Decouple currently integrating components  from availability of Atlas service 
> for raising metadata events

> The components that currently integrate with Atlas (Hive, Sqoop, Falcon, 
> Storm) all communicate their metadata events using Kafka as a messaging 
> layer. This effectively decouples these components from the Atlas server. 
> However, all of these components have some initialization that checks if 
> their respective models are registered with Atlas. For components that 
> integrate on the server, like HiveServer2 and Falcon, this initialization is 
> a one time check and hence, is manageable. Others like Sqoop, Storm and the 
> Hive CLI are client side components and hence the initialization happens for 
> every run or session of these components. Invoking the initialization (and 
> the one time check) every time like this effectively means that the Atlas 
> server should be always available.
> This JIRA is to try and remove this dependency and thus truly decouple these 
> components.
