Description

Hadoop does not set the "map.input.file" variable. I tried the fallowing and all I get is "null".

public class Map extends Mapper<Object, Text, LongWritable, Text> {

public void map(Object key, Text value, Context context)
throws IOException, InterruptedException

{ Configuration conf = context.getConfiguration(); System.out.println(conf.get("map.input.file")); }

protected void setup(Context context) throws IOException,
InterruptedException { Configuration conf = context.getConfiguration(); System.out.println(conf.get("map.input.file")); }

}
