Read key and values from HDFS
The ReduceTask can save the file using several output format:
InternalFileOutputFormant, SequenceFileOutputFormat
Hi Pedro i am not sure we have a single method for reading the data in
output files for different otutput formats.
But for sequence files we can use SequenceFile.Reader class in the API to
read the sequence files.

Hi,
Just use "hadoop fs -text ". It would read most of these files
without breaking a sweat :)
You can look at its implementation inside FsShell.java if you want to
implement/reuse things in Java.
