[jira] [Commented] (MAHOUT-1340) Make LuceneSegment* tests work with both Hadoop 1 and 2

    [ https://issues.apache.org/jira/browse/MAHOUT-1340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13776088#comment-13776088 ] 

Sean Owen commented on MAHOUT-1340:
-----------------------------------

Yep that's a good one. It passes versus 1.x, so can only help versus 2.x. :) I will commit unless anyone can see a reason not to. It's just a fix to a test after all.

> Hadoop changed a few classes to interfaces between Hadoop 1 and Hadoop 2. A couple of these classes are used in the LuceneSegment unit tests. A little bit of simple reflection abstracts these differences away and makes these tests pass under both Hadoop 1 and Hadoop 2.
