Class BayesFeatureOutputFormat
java.lang.Object
org.apache.hadoop.mapred.FileOutputFormat<K,V>
org.apache.hadoop.mapred.lib.MultipleOutputFormat<org.apache.hadoop.io.WritableComparable<?>,org.apache.hadoop.io.Writable>
org.apache.mahout.classifier.bayes.mapreduce.common.BayesFeatureOutputFormat
- All Implemented Interfaces:
- org.apache.hadoop.mapred.OutputFormat<org.apache.hadoop.io.WritableComparable<?>,org.apache.hadoop.io.Writable>
public class BayesFeatureOutputFormat
- extends org.apache.hadoop.mapred.lib.MultipleOutputFormat<org.apache.hadoop.io.WritableComparable<?>,org.apache.hadoop.io.Writable>
This class extends the MultipleOutputFormat, allowing to write the output data to different output files in
sequence file output format.
