Hi
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.
Requirement:
------------------
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};
Code:
--------
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());
column.setValue("value3".getBytes());
column.setTimestamp(System.currentTimeMillis());
// push data to cassandra
batchMutate.addInsertion(RowIdString, "CompositeColumnNameTest", column);
keyspaceServiceImpl.batchMutate(batchMutate);
Exception:
-------------
me.prettyprint.hector.api.exceptions.HInvalidRequestException:
InvalidRequestException(why:Not enough bytes to read value of component 0)
