Subject Map output compression in Hadoop 1.0.3
Date Wed, 28 Nov 2012 11:12:30 GMT

Quick question: What's the best way to turn on Map Output Compression in Hadoop 1.0.3? The
tutorial at http://hadoop.apache.org/docs/r1.0.3/mapred_tutorial.html says to use JobConf.setCompressMapOutput(boolean),
but I'm using o.a.h.mapreduce.Job rather than o.a.h.mapred.JobConf.

Is it simply a case of using getConf.set("mapred.output.compress", true) then constructing
my Job from the Configuration object, or is there more direct way that I've missed?
