[jira] [Created] (HADOOP-12048) many undeclared used dependencies (and declared unused dependencies)

Sangjin Lee created HADOOP-12048:
------------------------------------

             Summary: many undeclared used dependencies (and declared unused dependencies)
                 Key: HADOOP-12048
                 URL: https://issues.apache.org/jira/browse/HADOOP-12048
             Project: Hadoop Common
          Issue Type: Bug
          Components: build
    Affects Versions: 3.0.0
            Reporter: Sangjin Lee


Currently there are numerous undeclared used dependencies and declared unused dependencies in the hadoop projects.

Undeclared used dependencies are easier errors to correct, and correcting them will lead to a better management of dependencies (enabling stricter dependency frameworks down the road).

Declared unused dependencies are harder to resolve, as many may be legitimate runtime dependencies. But fixing them would lead to smaller profiles for hadoop projects.

We can do a one-time scan of dependency issues and fix them. However, in the long run, it would be nice to be able to enforce those rules via maven plug-in.
