Subject [jira] Updated: (HADOOP-851) Implement the LzoCodec with support for the lzo compression algorithms
Date Tue, 09 Jan 2007 22:17:27 GMT

Doug Cutting updated HADOOP-851:
--------------------------------

    Status: Open  (was: Patch Available)

I am able to build this without problem on Ubuntu Edgy.

Since liblzo2 isn't normally installed, I'm hesitant to include this in libhadoop.so, since
I think libhadoop.so would then no longer link unless folks have liblzo2 installed.  (This
is different from zlib, which is normally installed on most systems.)  It's a pain to build
a separate library, but I don't see an alternative.

Also, can you please add a unit test?  This should be a no-op when the native code isn't available.
 This could be a simple addition to TestSequenceFile#testSequenceFile, having it test another
codec.
