Cassandra 无法从键&u验证&u类=&x27;复合类型(UTF8Type,UTF8Type)和#x27;

Cassandra 无法从键&u验证&u类=&x27;复合类型(UTF8Type,UTF8Type)和#x27;,cassandra,thrift,Cassandra,Thrift,我正在尝试阅读卡桑德拉1.1.6。这是cassandra cli中的脚本 CREATE COLUMN FAMILY aaa with column_type = 'Standard' and comparator = 'UTF8Type' and default_validation_class = 'UTF8Type' and key_validation_class = 'CompositeType(UTF8Type,UTF8Type)'; 当我试着节约阅读的时候 c1.getColumn

我正在尝试阅读卡桑德拉1.1.6。这是cassandra cli中的脚本

CREATE COLUMN FAMILY aaa
with column_type = 'Standard'
and comparator = 'UTF8Type'
and default_validation_class = 'UTF8Type'
and key_validation_class = 'CompositeType(UTF8Type,UTF8Type)';
当我试着节约阅读的时候

c1.getColumn().getValue()
或与

client.get_slice(toByteBuffer(rowKey), parent, predicate, ConsistencyLevel.ONE);
我收到以下例外情况:

Exception in thread "main" InvalidRequestException(why:Not enough bytes to read value of component 0) 

如果在CLI中执行
列表aaa
,输出是什么?
