It's complaining that "-dt sequence" is invalid. It should be "-dt

Based on the book "Mahout in action", i was trying to use the

but I get the following error:

This is the command line:
mahout org.apache.mahout.clustering.lda.LDAPrintTopics -i
test3/simple-lda-sparse/state-10/ \
-d test3/simple-vectors/dictionary.file-* -dt sequence -w
10
I'm using mahout 0.5 in a local single node hadoop.
If someone have any idea about this error, please let me know.
Regards.
so... that was a very bad question... my judgment was just completely
focused
in that WARN and didn't read the subsequent output.. even when I paste
that
in this email :S.
Thank you so much.
