So I have two questions: 1) What I did wrong, must I define the complete structure of my column family before using json2sstable or is it the structure of my json file which is not good? I think that you just have to specify column_type = 'super' when creating your column family (see http://stackoverflow.com/questions/6835183/set-super-column-family-in-cassandra-cli) Paolo
