Cassandra 读取负帧大小

Question

我在尝试使用 cassandra-jdbc(1.1.3) 驱动程序查询 Cassandra 时遇到此错误。

Caused by: org.apache.thrift.transport.TTransportException: Read a negative frame size (-2147418110)!

这是我的示例代码片段

statement = connection.prepareStatement(SELECT_CQL);
statement.setString(1, ID);
resultSet = statement.executeQuery();

我假设您试图在 cql 端口 (9042) 上通过 JDBC 连接到 Cassandra。
我能够连接到它，从而实现节俭

nodetool enablethrift

然后连接到端口 9160(或您可能在 conf/cassandra.yaml 中覆盖的任何端口)。希望这可以帮助。
