Based on the book "Mahout in action", i was trying to use the
`LDAPrintTopics`,
but I get the following error:
WARN driver.MahoutDriver: No
org.apache.mahout.clustering.lda.LDAPrintTopics.props found on
classpath, will use command-line arguments only

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.
