> CassandraStorage improperly assumes all DataBags are DefaultDataBags. As a result, natural Pig code can't be used with CassandraStorage. For example:
> {quote}
> {{B = FOREACH A GENERATE $0, TOBAG(TOTUPLE($1, $2));}}
> {{STORE B into 'cassandra://MyKeySpace/MyColumnFamily' using CassandraStorage();}}
> {quote}
> fails with a complaint that a {{NonSpillableDataBag}} can't be converted into a {{DefaultDataBag}}.
> Since the {{CassandraStorage}} code only calls methods from {{DataBag}}, there is no need for this artifical restriction. After applying the attached patch, the above code works fine, making CassandraStorage much easier to use.
> This is my first submission to Cassandra, so I apologize for any incorrect process. Please let me know what I should do differently. In particular, I am a little unclear where I should put the test. I am thinking I should put it in ThriftColumnFamilyTest.java. Is this correct or should it be somewhere else? I'll create a test as soon as I understand.
