Johan Oskarsson commented on CASSANDRA-47:
------------------------------------------
While Lzo is great, it is unfortunately not compatible with the Apache license.
They had to remove it from Hadoop, see HADOOP-4874. In that ticket they mention
a couple of alternatives such as http://www.fastlz.org/ or lzf
http://h2database.googlecode.com/svn/trunk/h2/src/main/org/h2/compress/
It would be possible to do what Hadoop has done and released the lzo bindings
separately, but that would make it harder for users to find and use.
