Erik Bergenholtz commented on ATLAS-512:
----------------------------------------

I think you are right in that the main point is to remove dependencies, not 
handle model registration differently which is just one approach. Does 
separating model registration to some other mechanism (option 1||2) accoplish 
reducing the dependency graph?

> 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.
