Looks like validation class for composite column value is different than UTF8Type? Though code suggests it is:
       composite.addComponent("TEXT1", StringSerializer.get());

Please validate.

I have an issue while inserting a composite column name to one of the Cassandra column families. Below is a detailed description of what I had done and stuck up at.

Please let me know where I had went wrong.




       Rowkey        ->     RowIdString

       Column name   ->     TEXT1 : value1 : TEXT2 : value2 : TEXT3

       Column value ->     value3


Column family definition:


                create column family CompositeColumnNameTest

       WITH comparator='CompositeType(UTF8Type,UTF8Type,UTF8Type,UTF8Type,UTF8Type)'

       AND key_validation_class=UTF8Type

       WITH compression_options={sstable_compression:SnappyCompressor, chunk_length_kb:64};




                String RowIdString = "1234";


       Composite composite = new Composite();

       composite.addComponent("TEXT1", StringSerializer.get());

       composite.addComponent("value1", StringSerializer.get());

       composite.addComponent("TEXT2", StringSerializer.get());

       composite.addComponent("value3", StringSerializer.get());

       composite.addComponent("TEXT3", StringSerializer.get());


       Column column = new Column(composite.serialize());




       // push data to cassandra

       batchMutate.addInsertion(RowIdString, "CompositeColumnNameTest", column);
