Yep - it's usable and separate so you should be able to download =
0.7-branch and build the jar and use it against a 0.7.3 cluster.  I've =
been using it against a 0.7.2 cluster actually.

http://svn.apache.org/repos/asf/cassandra/branches/cassandra-0.7/

To use it, check out the readme in the contrib/pig directory in the 0.7 =
branch.  One trivial example of copying one column family to another is:

rows =3D LOAD 'cassandra://Keyspace1/Standard1' USING =
CassandraStorage();
STORE rows INTO 'cassandra://Keyspace1/Standard2' USING =
CassandraStorage();

using the contrib/pig/pig_cassandra script (tx to brandon for that =
example).  Also make sure that Standard2 exists too.

If you have any other questions talk to jeromatron (me), driftx =
(brandon), or mvdir (eldon) in #cassandra or #hadoop-pig on IRC on =
freenode.
