Mapreduce decompress s3 file

[tachu]

Having trouble getting a file from s3 decompressed on the fly. here is the command we are trying

/usr/bin/hadoop jar /usr/lib/hadoop/hadoop-streaming.jar -libjars /home/hadoop/hadoop-xz-1.0.jar -Dmapred.output.compress=false -Dmapred.compress.map.out=false -Dmapred.input.compression.codec=io.sensesecure.hadoop.xz.XZCodec -Dmapred.map.tasks=1 -Dmapred.reduce.tasks=0 -input s3n://XXX/2013-05-02.txt.xz -output s3n://XXX/20130501_resultt -mapper /bin/cat -reducer /bin/cat

We basically are trying to decompress a file on the fly. this example would just write it back to s3 so far it just writes back the compressed data.
