[jira] Commented: (HADOOP-4605) should run old version of unit tests to check back-compatibility

    [ https://issues.apache.org/jira/browse/HADOOP-4605?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12645599#action_12645599 ] 

Doug Cutting commented on HADOOP-4605:
--------------------------------------

We could add a property to build.xml with a subversion URL.  This would point to a tagged release.  The unit tests of that release would be retrieved from subversion, compiled and run against the current core code.  We could use current versions of MiniDFSCluster and MiniMRCluster and daemons to test wire back-compatibility.  We could also run current tests against old versions of the daemons.
