-------------------------------------------------------------------
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. Any idea ?

version ?
