----------------------------------------------------------------

Hello [~almeidajeff] 

Thanks for your answer, it worked! I loaded the file in that folder and Ranger 
recognised the Druid service. I'm currently trying to follow the steps in your 
repo about loading the plugin in Druid.

I keep getting "Could not resolve type id 'ranger' as a subtype of 
`org.apache.druid.server.security.Authorizer`", even though I loaded the .jar 
file and the .xml files in the right folder of every Druid service (and 
modified .xml accordingly to my build). 

I followed official documentation and declared: 
druid.auth.authorizers=["ranger"], druid.auth.authorizer.ranger.type=ranger. 
Also, I added "ranger" in druid.extensions.loadlist.

Is there any key step I'm missing? Thank you for your contribution

problem:`java.lang.NullPointerException`", even though I loaded the .jar file

changes. Thank you for your contribution

> Druid is a high-performance, column-oriented, distributed data store, which 
> has an extension mechanism to incorporate various functionalities, for 
> example an external authorization system - just like ranger.
