I am ussing this schema created with cassandra-cli:

CREATE COLUMN FAMILY
    Relationships
WITH
    key_validation_class = 'CompositeType(UTF8Type, UTF8Type)'
AND
    comparator = UTF8Type
AND
    default_validation_class = IntegerType
;
from https://github.com/amorton/wdcnz-2012-site/blob/master/cassandra-schema.txt

I am using cassandra 1.1.6. I want to have a composite rowkey, i can insert with thrift but when i try to get the information from a row i have this exception

this exception using get.client
