(I'm using Cassandra 1.2.8 and Pig 0.11.1)
I'm loading some simple data from Cassandra into Pig using CqlStorage. The
CqlStorage loader defines a Pig schema based on the Cassandra schema, but
it seems to be wrong.
If I do:
data = LOAD 'cql://bookdata/books' USING CqlStorage();
DESCRIBE data;

I've checked out and built the 1.2.10-tentative branch, and I've noticed
that all of my CQL prepared statements are now broken.
Looking into the code, it looks like the "#" -> "=" and "@" -> "?"
translations were removed. I tried to replace these in one of my scripts
with "=" and "?", but there's
I don't see this formally documented anywhere, so I thought I'd give a
heads-up to folks using Pig with Cassandra.
In pre-1.2.10 versions, storing data into Cassandra required a query like
this:
STORE data INTO 'cql://keyspace/table?output_query=update table set
some_value @ #' USING CqlStorage();
As an FYI, creating the table without the "WITH COMPACT STORAGE" and using
CqlStorage works just fine in 1.2.10.
I know that CqlStorage and AbstractCassandraStorage got changed for 1.2.10
- maybe there's a regression with the existing CassandraStorage?

The OP was using a Thrift table and CassandraStorage. I verified that the
problem does not exist with a CQL3 table and CqlStorage.
