This is a follow up jira from
1. Now with the findbug warning：
As discussed in
Why was this committed with a findbugs errors rather than adding the necessary plumbing in pom.xml to make it go away?
we will add the findbugsExcludeFile.xml and will get rid of this given kerby-1.0.0-rc3 release.
2. Add the kerby version hadoop-project/pom.xml
hadoop-project/pom.xml contains the dependencies of all libraries used in all modules of hadoop, under dependencyManagement. Only here version will be mentioned. All other Hadoop Modules will inherit hadoop-project, so all submodules will use the same version. In submodule, version need not be mentioned in pom.xml. This will make version management easier.
