Cassandra & Pig

  Does anyone know of any good tutorials for using Pig with Cassandra?

I am trying do a basic load:

rows = LOAD 'cassandra://Foo/Bar' USING CassandraStorage();

but i keep getting this error.

ERROR 1070: Could not resolve CassandraStorage using imports: [, 
org.apache.pig.builtin., org.apache.pig.impl.builtin.]

Where is this class.. Cassandra or Pig? More importantly how do I 
register it with Pig?

Thanks!

Hi

did you register cassandra jars with Pig. This seems like a class  
loading problem.

Details of basic linkage are in the contrib/pig section of the
Cassandra source in the readme.  You should be able to run basic
queries with just that.
