Hi everyone,

  Using Hadoop-0.20.2, I'm trying to use MultiFileInputFormat which is =
supposed to put each file from the input directory in a SEPARATE split. =
So the number of Maps is equal to the number of input files. Yet, what I =
get is that each split contains multiple paths of input files, hence # =
of maps is < # of input files. Is it because "MultiFileInputFormat" is =
deprecated?

  In my implemented myMultiFileInputFormat I have only the following:

public RecordReader<LongWritable, Text> getRecordReader(InputSplit =
split, JobConf job, Reporter reporter){
		return (new myRecordReader((MultiFileSplit) split));
	}

Yet, in myRecordReader, for example one split has the following;
 =20
  " /tmp/input/file1:0+300
    /tmp/input/file2:0+199  "

  instead of each line in its own split.

    Why? Any clues?

          Thank you,
              Maha
