> I ran VectorDumper from the command line like this:
> $MAHOUT_HOME/bin/mahout vectordump -i ${HDFS_VECTS} --csv -p > ${LOCAL_VECTS}
> I've used this command before to dump similar vectors, but I'm now getting missing argument
> ERROR common.AbstractJob: Missing value(s) --printKey
> You can add an argument after each of these flags to work around this problem for now:
> $MAHOUT_HOME/bin/mahout vectordump -i ${INPATH} --csv x -p x > ${LOCAL_OUT}
> I encountered this on the trunk, but I think it's likely this problem went out in 0.6;
I can check in the next fews days if nobody does it first.
