I've been fiddling with the unit tests for compression codecs to demonstrate
basic installation functionality:
"java org/apache/hadoop/io/compress/TestCodec -codec
org.apache.hadoop.io.compress.SnappyCodec" seems to be working ok for snappy.

Subject: Re: LZO Compression
Email was sent a bit prematurely.
Anyway. How can one test that LZO compression is configured correctly?
I've found multiple sources on how to compile the hadoop-lzo jars and
native files but no where did I see a definitive way to test that the
installation/configuration is correct.
Also, when is this compression enabled? Is it enabled on every file I
write? Do I somehow have to specify that I want to use this format? For
example we have a rather large directory of server logs ...
/user/mark/logs. How can we enable compression on this directory?
Thanks for your help
