---------------------------------
Hello Kang,
Could you explain the rationale behind this? Files are already decompressed by
{{-cat}}, etc. shell utils, native programs like lzo's.
If its for testing native lib loads, or compression codec loading, we already
have TestCodec for that, which I've once explained how to use at:
http://search-hadoop.com/m/RqwE52Sh1GI
Given these two facts, I believe the only usefulness of adding this is to
compress a file given a codec? Perhaps TestCodec may be extended to provide
such a utility as well?

> It can be used as follows:
> compress a.txt to a.lzo:
> hadoop jar test.jar org.apache.hadoop.io.compress.CodecTool
> org.apache.hadoop.io.compress.LzoCodec -c 1024 1024 a.txt a.lzo
> decompress a.lzo to stdout:
> hadoop jar test.jar org.apache.hadoop.io.compress.CodecTool
> org.apache.hadoop.io.compress.LzoCodec -x 1024 1024 a.lzo /dev/stdout
