Mahout Cookbook - Weird FileNotFoundException - hadoop

Question

I'm following the mahout cookbook example. In one of them, I'm getting an exception:
mahout seqdirectory -i /home/hduser/cook/lastfm/current -o /home/hduser/cook/lastfm sequencefiles/
And then, I'm getting the following exception:

The problem is that the folder exists, as shown here:
hduser#ACER-V3-571G:~/cook/lastfm/current$ ls
artists.txt ArtistTags.dat README.txt tags.txt
Mahout 0.9 and Hadoop 2.2.0
jps shows me:
5435 ResourceManager
7257 Jps
5531 NodeManager
5104 DataNode
5262 SecondaryNameNode
5008 NameNode

Answer 1

I'm sorry, but i found the solution by myself.
Since the file isn't in the Hadoop Filesystem, I should run mahout as local.
export MAHOUT_LOCAL=TRUE
solves the problem.

Answer 2

Since an "export" configures a system environment variable in unix, an similar command should do it in Windows. Try:
SET MAHOUT_LOCAL=TRUE
