             Summary: Remove default dependencies from hadoop-ozone project
                 Key: HDDS-1113
                 URL: https://issues.apache.org/jira/browse/HDDS-1113
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
          Components: build
            Reporter: Elek, Marton
            Assignee: Elek, Marton


There are two ways to define common dependencies with maven:

  1.) put all the dependencies to the parent project and inherit them
  2.) get all the dependencies via transitive dependencies

TLDR; I would like to switch from 1 to 2 in hadoop-ozone

My main problem with the first approach that all the child project get a lot of dependencies independent if they need them or not. Let's imagine that I would like to create a new project (for example a java csi implementation) It doesn't need ozone-client, ozone-common etc, in fact it conflicts with ozone-client. But these jars are always added as of now.

Using transitive dependencies is more safe: we can add the dependencies where we need them and all of the other dependent projects will use them.
