I am not able to reproduce it, however I did face similar problem once.
Look into ClusterClassificationDriverTest's
testVectorClassificationWithOutlierRemovalMR method. Here I am
explicitly deleting the classifiedOutputPath.
If I don't delete it, I get a similar error ( similar to
Output directory
file:/tmp/mahout-TestDistributedRowMatrix-1962901348178391040/testdata/transpose-65
already exists).
when I run it for second time.
Explicitly deleting the file might help in the test case ( I agree that
this is not the best solution, but, I am not able to find the actual
problem for such behavior ).

Unfortunately, I can't duplicate this test failure. Is this something
that may clear itself up when the next timer-initiated build starts?
If anyone out there can duplicate the test failure, please let me know
what OS/Java version you are using. You can run just the one test with:
mvn -U -DfailIfNoTests=false -Dtest=TestDistributedRowMatrix test

Mahout needs to be made compatible with Hadoop .23 releases

Project: Mahout
Issue Type: Improvement
Components: build
Affects Versions: 0.6
Reporter: Roman Shaposhnik
Assignee: tom pierce
Labels: bigtop

As part of the Hadoop stack integration project (Apache Bigtop) we
are now trying to compile Mahout's upcoming 0.6 release against
Hadoop 0.22 and 0.23.
I'm attaching the patch to Mahout's Maven build system that made it
possible. I would also like to request help in solving the real
issues that poped
up when we tried to compile Mahout:
