Question

我在Cassandra 2.0.7中使用thrift Api创建动态列族并插入long值。但它的投掷错误只适用于长型。其他类型如string，int和byte正在工作。

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;

代码：

public ColumnOrSuperColumn createColumnOrSuperColumn（String name， long long，long timestamp）抛出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;

}

我需要进行任何其他转换来解决此问题吗？

如果有人有想法，请告诉我。

Answer 1

我在创建键空间时删除了default_validation_class。然后插入包括长值。

感谢您的支持

Answer 2

请更改您的

default_validation_class = UTF8Type to default_validation_class = LongType

它应该有用。

cassandra thrift long insert - InvalidRequestException（why :( String未验证。）
