Hadoop: How to generate custom reduce output file name?

Question

Now, I use MultipuleOuputs. I would like to remove the suffix string "-00001" from reducer's output filename such as "xxxx-[r/m]-00001".

Is there any idea?

Thanks.

Answer 1

From Hadoop javadoc to the write() method of MultipleOutputs:

Output path is a unique file generated for the namedOutput. For example, {namedOutput}-(m|r)-{part-number}

So you need to rename or merge these files on the HDFS.
