hi all, i'm at my last step for thesi,covert an arff file in a vector. I founded this,as like suggested in an old post: https://cwiki.apache.org/MAHOUT/creating-vectors-from-wekas-arff-format.html
I did two different attempted: 1) From trunk folder I moved in trunk/utils and then I used mvn install but when i get the snapshoot and i try to run Driver.class i took this error message: java.lang.ClassNotFoundException:org.apache.commons.cli2.OptionException so i attempted another way: i looked inside Driver.java to see the imports: import org.apache.commons.cli2.CommandLine; import org.apache.commons.cli2.Group; import org.apache.commons.cli2.Option; import org.apache.commons.cli2.OptionException; import org.apache.commons.cli2.builder.ArgumentBuilder; import org.apache.commons.cli2.builder.DefaultOptionBuilder; import org.apache.commons.cli2.builder.GroupBuilder; import org.apache.commons.cli2.commandline.Parser; import org.apache.hadoop.conf.Configuration; import org.apache.hadoop.fs.FileSystem; import org.apache.hadoop.fs.Path; import org.apache.hadoop.io.LongWritable; import org.apache.hadoop.io.SequenceFile; import org.apache.mahout.common.CommandLineUtil; import org.apache.mahout.math.Vector; import org.apache.mahout.math.VectorWritable; import org.apache.mahout.utils.vectors.io.JWriterVectorWriter; import org.apache.mahout.utils.vectors.io.SequenceFileVectorWriter; import org.apache.mahout.utils.vectors.io.VectorWriter; import org.slf4j.Logger; import org.slf4j.LoggerFactory; and then to compile it directly,but didn't work. any suggestion?? any guide on Mahout's vector format so i can try to make from my own a converter?
