[jira] [Issue Comment Edited] (HADOOP-7952) simplify common back to a single jar

    [ https://issues.apache.org/jira/browse/HADOOP-7952?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13179889#comment-13179889 ]

---------------------------------------------------------------

The fact that there is a dependence loop between the stuff in auth and common is indicative of a problem. To address that you pulled the annotations out, but that just makes the whole structure very complex.

I'd suggest a structure that looks like:
* common
* hdfs
  ** hdfs-client
  ** hdfs-server
* yarn
  ** yarn-client
  ** yarn-server
* mapreduce
* extras
  ** distcp
  ** har
  ** httpfs
* examples

If you want to add an extra project that pulls auth package out of the common jar, I guess we could do it that way. That way, the base case for Hadoop works well and it is easy to find things.
