Lance Norskog commented on MAHOUT-838:
--------------------------------------
The November 1 patch is correct:
https://issues.apache.org/jira/secure/attachment/12501764/MAHOUT-838.patch
md5: 41577c6103f8feaf3b44dee9efe53255
Apply this to a fresh trunk. All of the tests run, and the two jobs run.
There is one line that changes a HashMap to a LinkedHashMap, and that should
not be there. Formatting problems- some existing code has funny indentation and
this patch corrects it. Other than that, this is finished.
> Make the confusion matrix writable to a file when testing classifiers
