Hi,
In my hadoop running example, the data ouput is compressed using gzip. I would
like to create a small java program that decompress the output. Can anyone
give an example on how to decompress the output in java using the hadoop API?

Best regards,

would not a shell program be better suited?
just inquisitive.

Write a Ja
first of ll, I would like to create a java program and not using shell
commands.
But your question brings me another one. If java already contains classes to
compress data, why hadoop mapreduce created their own class like
./org/apache/hadoop/io/compress/GzipCodec.java?

I think the 'hadoop fs -text' command may just be what you need.
It decompresses various formats by itself, and gzip for both Sequence
and Text files is included in its feature set.
