Tom Beerbower commented on ATLAS-512:
-------------------------------------
[~yhemanth], Sorry, I was thinking that the primary reason for the decoupling
was to remove the dependencies.
Isn't model registration still bound to an active Atlas server for option 1? In
other words, isn't the integration deployment blocked until the Atlas server is
started anyway? You can't deploy the integration until you successfully run
the tool, which requires Atlas to be running.

> 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.
