Not sure what's so disappointing here, it was never officially announced that
Mahout 0.9 had Hadoop 2.x support.
From trunk, can you build mahout for hadoop2 using this command:
mvn clean package -Dhadoop2.version=YOUR_HADOOP2_VERSION

You have upper-case in your command but lower-case in your declaration in
the properties file; correct that and it should work.
Note:
org.apache.mahout.text.wikipedia.WikipediaXmlSplitter =
wikipediaXmlSplitter : wikipedia splitter
hadoop@solaris:~/mahout-distribution-0.9$ bin/mahout
Thanks Andrew, that seems to have been the issue all the while.
Nevertheless, it is better to run from Head if running on Hadoop 2.3.0

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

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 :
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
see the complete log
hadoop@solaris:~/mahout-distribution-0.9$ head -n 5
src/conf/driver.classes.default.props
FYI, I am trying to complete the wikipedia example from Apache's document
https://cwiki.apache.org/confluence/display/MAHOUT/Wikipedia+Bayes+Example

Mahmood

The example as documented on the Wiki should work. The issue u seem to be
running Mahout 0.9 distro that was built with hadoop 1.2.1 profile on a Hadoop
2.3 environment. I don't think that's gonna work.
Suggest that you either:
a) Switch to a Hadoop 1.2.1 environment
b) Work off of present
That is rather disappointing
b) Work off of present Head and build with Hadoop 2.x profile.
Can you explain more?

Mahmood

Thank you two and I really appreciate it! Wish you two very successful in

I was wondering is there any documentation or tutorial which can go through
how the Hadoop is written, not like the definition guide one.
For example, from the very
when run the command like:
mahout seq2sparse -i inputfile -o outputfile
where is the command seq2sparse defined? how does the system know to
actually run the SparseFileFromSequenceFile class?
what is the language used in the command Mahout such as the language given
below:
Those aliases are defined in src/conf/driver.classes.default.props.
That language is shell-scripting, e.g. bash.

That's a bash script that invokes a Java class - MahoutDriver which reads the
props file mentioned earlier.
The props files is a mapping of the commandName to the actual Java program.
For Eg:- seq2sparse would be mapped to SparseVectorsFromSequenceFiles in the
props.

I can run the examples under the mahout-distribution directory fine.
However cannot run the bin/mahout command, gives following errors.
mvn exec runs ok fine with mainClass (standard syntax) given (ran few
example classes from cf.taste and they run fine)
Following is command that gives error
Did you build Mahout?

I think you need mvn package to create artifacts but that is just a first
simple guess.

Independent of maven: you are using an old version of Mahout. You may find
that some of the programs work better in the trunk than in the 0.5 release.
Also, the wiki documentation generally moves forward with the current trunk
and so it may be confusing.
