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.
