store to defined filename

Hi,

Is it possible to store results in to a file with determined filename, 
instead of part-r-00000? How to do that?

Hi there,

You could do that with the help of
MultipleOutputFormat<http://hadoop.apache.org/docs/current/api/org/apache/hadoop/mapred/lib/MultipleOutputFormat.html>class.
It extends FileOutputFormat,and allows us to write the output data
to different output files.

You can either do Hadoop "mv" if its a wrapper script or 

do getMerge to merge and rename all part files to single part file.
