> Provide shaded artifact to start ozone service as a datanode plugin
> -------------------------------------------------------------------

>                 Key: HDDS-446
>                 URL: https://issues.apache.org/jira/browse/HDDS-446
>             Project: Hadoop Distributed Data Store
>          Issue Type: Improvement
>            Reporter: Elek, Marton
>            Assignee: Elek, Marton
>            Priority: Major
>             Fix For: 0.2.1

>         Attachments: HDDS-446-ozone-0.2.001.patch
>
>
> Ozone datanode service could be started in two different way:
>  # as a standalone process
>  # as a datanode plugin
> We tested the second scenarion by compiling both ozone + hadoop trunk 
> together and created a combined artifact. But we have no more full hadoop 
> distribution in the ozone release package any more. And we had no answer how 
> it could be started with an existing hadoop release.
> We need a well defined way to add the datanode-service to the classpath of 
> the hadoop datanode.
> I propose here to create a lightweight shaded artifact (and here the shading 
> only combines all the classes together without package name refactoring) to 
> make it easier to extend an existing hadoop installation.
> In this patch I add the shade plugin execution to the ozone 
> objectstore-service and the shaded file will be copied to the distribution.
> A new docker-compose based execution environment (ozone-hdfs) 
> demonstrates/tests how it could work.
> Tested with hadoop 3.1.0 and datanode service could be started without any 
> problem
