how to give a custom name to hadoop output files

Question

I want the output files in the format as 2012117-part-r-00000. Basically I want the output file to have the date appended to it, so that I can arrange the files according to date. I looked at OutputFormat and FileOutputFormat, but it doesn't help my case.

Answer 1

I just found out for the new API, I can use org.apache.hadoop.mapreduce.lib.output.MultipleOutputs and the method addNamedOutput()
