As the previous email says, you must be using Windows, and as far as I
remember, first you need Cygwin and then to solve the permissions issue
you need to downgrade to version 0.20.2. I think Mahout 0.7 depends on
Hadoop 0.20.204, so you will get the permissions error on Windows and
you will get the permissions issue from that version onwards (not sure
if it 2.0.0-alpha falls into this group). There is a workaround for it,
but it is quite convoluted.

copy you code and try to run it on hadoop cluseter.

????: mahout lib : permissions
Hi mahouters,
I am trying to use the mahout lib with my app java.
But while I try to clusterize calling this:
DocumentProcessor.tokenizeDocuments(new
Path(inputDir),analyzer.getClass().asSubclass(Analyzer.class), tokenizedPath,
conf);
And this:
InputDriver.runJob(new Path(inputDir), tokenizedPath,
"org.apache.mahout.math.RandomAccessSparseVector");
I have this error:
Exception in thread "main" java.io.IOException: Failed to set permissions of
