You said all versions. However, when I try to access cassandra://twissandra/users based on http://www.datastax.com/docs/1.0/dml/using_cql I get :

Or only with 1.2? We are using astyanax library, which seems to fail horribly on 1.2, so we're still on 1.1.8. But we're just starting out with this and i'm still debating between cassandra and hbase. So I just want to know if there is a limitation here or not, as I have no idea when 1.2 support will exist in astyanax. That said, are there other java (scala) libraries that people use to connect to cassandra that support 1.2? -James- On Thu, Jan 17, 2013 at 8:30 AM, <cscetbon....@orange.com<mailto:cscetbon....@orange.com>> wrote: Ok, I understand that I need to manage both cassandra and hadoop components and that pig will use hadoop components to launch its tasks which will use Cassandra as the Storage engine.

The testing I have done, had Hadoop and Cassandra Nodes collocated on the same hosts. Remember that Pig code runs inside of your hadoop cluster, and connects to Cassandra as the Database engine. I have not done any testing with Hive, so someone else will have to answer that question.

I just want to use pig and hive on cassandra. I know that pig samples are provided and work now with cassandra natively (they are part of the core). However, does it mean that the process will be spread over nodes with number_of_mapper=number_of_nodes or something like that ? Can Hive connect to Cassandra 1.2 easily too ? -- Cyril Scetbon On Jan 17, 2013, at 2:42 PM, James Schappet <jschap...@gmail.com<mailto:jschap...@gmail.com>> wrote: CFS is Cassandra File System: http://www.datastax.com/dev/blog/cassandra-file-system-design But you don't need CFS to connect from PIG to Cassandra.
