Okay I'm using your code but I was using CassandraStorageHandler instead of CqlStorageHandler
in the Hive DDL command :( Is there a documentation somewhere which describes how to use your
driver ? I don't have any issue when I use CassandraStorageHandler with a cql2 table, but
when I use CqlStorageHandler with a cql3 table I get :

java.io.IOException: java.lang.ClassCastException: org.apache.hadoop.io.MapWritable cannot
be cast to org.apache.hadoop.io.WritableComparable
        at org.apache.hadoop.hive.ql.exec.FetchOperator.getNextRow(FetchOperator.java:521)

FYI, I use Hadoop 1.2.1 (as Hadoop 2 is not supported) and tried with both hive 0.10.0 and
0.11.0. I also tried with Hadoop 0.20.2 as you use version 0.20.205.0 as a dependancy in the
maven configuration file (pom.xml).

Any idea ?

> The standalone hive support (at https://github.com/riptano/hive) would be great to have
in-tree so that people don't have to go out to github to download it and wonder if it's a
left-for-dead external shim.
