[jira] [Commented] (HADOOP-16959) resolve the dependency conflict

    [ https://issues.apache.org/jira/browse/HADOOP-16959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17077114#comment-17077114 ] 

Steve Loughran commented on HADOOP-16959:
-----------------------------------------

The best way to prevent this is not to declare versions of dependencies in the -cos subdir, but in hadoop-project/pom.xml and pick them up there.

if they are coming in from other dependencies, its still good to declare those external ones in hadoop-project and exclude the transient ones causing trouble

thanks
