[jira] [Created] (HADOOP-8278) Make sure components declare correct set of dependencies

Make sure components declare correct set of dependencies
--------------------------------------------------------

                 Key: HADOOP-8278
                 URL: https://issues.apache.org/jira/browse/HADOOP-8278
             Project: Hadoop Common
          Issue Type: Improvement
          Components: build
            Reporter: Tom White


As mentioned by Scott Carey in https://issues.apache.org/jira/browse/MAPREDUCE-3378?focusedCommentId=13173437&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13173437, we need to make sure that components are declaring the correct set of dependencies. In current trunk there are errors of omission and commission (as reported by 'mvn dependency:analyze'):
* "Used undeclared dependencies" - these are dependencies that are being met transitively. They should be added explicitly as "compile" or "provided" scope.
* "Unused declared dependencies" - these are dependencies that are not needed for compilation, although they may be needed at runtime. They certainly should not be "compile" scope - they should either be removed or marked as "runtime" or "test" scope.
