In fact, see this file
src/conf/driver.classes.default.props
which is not exactly as what you said. Still I have the same problem. Please

Mehmood,
wikipediaXMLSplitter is not present in driver.classes.default.props. To
accomplish what u r trying to do, u can edit
src/conf/driver.classes/default/props and add an entry for wikipediaXMLSplitter.
org.apache.mahout.text.wikipedia.WikipediaXmlSplitter = wikipediaXmlSplitter :
wikipedia splitter
You should then be able to invoke via:
mahout wikipediaXmlSplitter -d<path> -o<path> -c64
please give that a try.

Hi
When I run
mahout wikipediaXMLSplitter -d
examples/temp/enwiki-latest-pages-articles.xml -o wikipedia/chunks -c 64
I get this error

However the wikipediaXMLSplitter exists in
mahout-distribution-0.9/integration/src/main/java/org/apache/mahout/text/wikipedia/WikipediaXmlSplitter.java
I know that it is possible to pass the full path but is there any way to define
a variable that points to the correct location. Something like
export
WIKI=mahout-distribution-0.9/integration/src/main/java/org/apache/mahout/text/wikipedia/
Where should I add that?

Mahmood
