Harsh J commented on MAPREDUCE-4773:
------------------------------------
The specific method:
http://hadoop.apache.org/docs/current/api/org/apache/hadoop/mapreduce/lib/output/MultipleOutputs.html#write(KEYOUT,%20VALUEOUT,%20java.lang.String)
in new API MO, allows you to specify calls such as {{mo.write(keyObj, valObj,
"dynamic/custom/subdir/path/string");}}. This ends up writing in job output dir
subdirectory {{dynamic/custom/subdir}} with partitioned files prefixed with
{{string-}}.
> MultipleOutput with different output path for each

> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Reporter: Rohit Dandona
>
> Is it possible to have multiple outputs in a map reduce code where each
> output is directed to a different path ?
> e.g.
> FileOutputFormat.setOutputPath(job, new Path(outputPath));
> MultipleOutputs.addNamedOutput(job, "Output 1", TextOutputFormat.class,
> Text.class, Text.class);
> MultipleOutputs.addNamedOutput(job, "Output 2", TextOutputFormat.class,
> Text.class, Text.class);
> Can "Output 1" & "Output 2" be alloted seperate paths ?
