cassandra thrift long insert - InvalidRequestException(why:(String didn't validate.)

Question

I'm creating dynamic column family and inserting long value by using thrift Api in Cassandra 2.0.7. But its throwing error only for long type. Other types like string , int and byte are working.

InvalidRequestException(why:(String didn't validate.) [Monitor][Groups][since] failed validation)

CREATE COLUMN FAMILY Groups
WITH comparator = UTF8Type
AND key_validation_class=UTF8Type
AND default_validation_class = UTF8Type;

Code :

public ColumnOrSuperColumn createColumnOrSuperColumn(String name, long value, long timestamp) throws UnsupportedEncodingException {

ByteBuffer buffer = ByteBuffer.allocate(Long.SIZE);
buffer.putLong(value);

Column column = new Column(ByteBuffer.wrap(name.getBytes("utf-8")));
column.setValue(ByteBuffer.wrap(buffer.array()));
column.setTimestamp(timestamp);

ColumnOrSuperColumn c = new ColumnOrSuperColumn();
c.setColumn(column);
return c;

}

I need to do any other conversion to resolve this issue?

Please advise me if anyone have idea.

Answer 1

I have removed the default_validation_class while creating the keyspace.Then insert is happening including long values.

Thanks for your support

Answer 2

Please change your

default_validation_class = UTF8Type to default_validation_class = LongType

It should work.
