    [ https://issues.apache.org/jira/browse/MAHOUT-840?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13157518#comment-13157518 ] 

Deneche A. Hakim commented on MAHOUT-840:
-----------------------------------------

Thanks for the patch. I tried it but I am getting errors in the following tests:


  testBuild(org.apache.mahout.classifier.df.builder.InfiniteRecursionTest): org.apache.mahout.classifier.df.node.Leaf.<init>(I)V
  testProcessOutput(org.apache.mahout.classifier.df.mapreduce.partial.PartialBuilderTest): org.apache.mahout.classifier.df.node.Leaf.<init>(I)V
  testMapper(org.apache.mahout.classifier.df.mapreduce.partial.Step1MapperTest): org.apache.mahout.classifier.df.node.Leaf.<init>(I)V
  testReadTree(org.apache.mahout.classifier.df.node.NodeTest): org.apache.mahout.classifier.df.node.Leaf.<init>(I)V
  testReadLeaf(org.apache.mahout.classifier.df.node.NodeTest): org.apache.mahout.classifier.df.node.Leaf.<init>(I)V
  testParseNumerical(org.apache.mahout.classifier.df.node.NodeTest): org.apache.mahout.classifier.df.node.Leaf.<init>(I)V

are you getting those errors too ?
