mahout command problems
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
mahout-distribution-0.5$ bin/mahout
no HADOOP_HOME set, running locally

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.

mvn install is the better command for this stuff.
"mvn install -DskipTests"

Did you also run a mvn package from the mahout root directory?

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