Create CF in Mapper's setup

[al...@ceid.upatras.gr]

I'd like to have a Hadoop MapReduce job create a column family in the
setup() method of the Mapper, if it doesn't already exist. How would I do
that correctly? I thought of using CassandraServer's methods (which is a
bit of a hack, I know), but they are private, so I suppose there is a
better way. Any help?

Thank you, I hadn't realized I should use thrift.

Download the source version of the latest 0.7 from http://cassandra.apache.org/download/ and take a look at the contrib/word_count example.  Specifically, in the contrib/word_count/src/WordCountSetup.java file, there are examples of how to create a column family using thrift.
