File Not Found Exception

[Keith Thompson <kt...@binghamton.edu>]

I am trying to run the arff.vector algorithm but am getting a File Not Found
Exception on my input directory.  I have checked and double-checked.  The
input path is definitely correct.  Someone suggested it could be a problem
that my Hadoop folder and my Mahout folder aren't in the same folder, but I
was able to run the Dirchlet clustering algorithm successfully specifying
both the --input and --output paths so I don't think that is the problem.
What other problems could cause this error to pop up?

To be more specific ... I can run bin/mahout seqdirectory -i <input> -o
<output> and it works. If I try to run bin/mahout arff.vector -i <input>
-o<output> with the same input file path, it says File Not Found.  Something
about that doesn't seem right ...

I just gave hdfs://localhost/path/to/file a try but that still produced the
error (would localhost be the right thing to use there?).  When I echoed
$HADOOP_CONF_PATH and $HADOOP_PATH they were both empty.  Where should those
be pointing?

If the path is for a file in HDFS, I have had problems where the 
hadoop tasks think the path is a local path, not an HDFS path. I think 
this happened to me because my HADOOP_CONF_PATH and HADOOP_PATH 
weren't set to a place that had HDFS as default. If that doesn't work, 
you can always try the fully qualified path 
(hdfs://server:port/path/to/file).
