--------------------------------------
Summary: Improvement to MultipleOutputs javadocs
Key: MAPREDUCE-4616
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4616
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: documentation
Affects Versions: 1.0.3
Reporter: Tony Burton
Priority: Minor
Fix For: trunk
In the new API, and using MultipleOutputs it is possible to segment output into
directories by using MultipleOutputs.write(KEYOUT key, VALUEOUT value, String
baseOutputPath) in the Reducer to determine the output directory, and by using
LazyOutputFormat at the job-level config to suppress normal output [eg use
LazyOutputFormat.setOutputFormatClass(job, TextOutputFormat.class); instead of
job.setOutputFormatClass(TextOutputFormat.class);]
This recreates the functionality previously provided in the old API by using
MultipleTextOutputFormat (etc)
