Question

我的Java代码：

public static void main(String[] args) {
    Cluster cluster;
    Session session;

    cluster = Cluster.builder()
                .addContactPoint("127.0.0.1")
                .withPort(9042)
                .build();

    session = cluster.connect("Bundesliga");

    session.execute("INSERT INTO test(c1,c2,c3,c4,c5) VALUES(0,0,0,0,0)");
}

错误讯息：

线程中的异常＆＃34; main＆＃34; com.datastax.driver.core.exceptions.NoHostAvailableException：全部尝试查询失败的主机（尝试：/127.0.0.1:9042（null））at com.datastax.driver.core.ControlConnection.reconnectInternal（ControlConnection.java:196）在 com.datastax.driver.core.ControlConnection.connect（ControlConnection.java:80）在com.datastax.driver.core.Cluster $ Manager.init（Cluster.java:1145）在com.datastax.driver.core.Cluster.init（Cluster.java:149）at com.datastax.driver.core.Cluster.connect（Cluster.java:225）at com.datastax.driver.core.Cluster.connect（Cluster.java:258）at cassandra.cassandra_main.main（cassandra_main.java:19）

我已查看cassandra.yaml：

start_native_transport：true

native_transport_port：9042

Answer 1

我修好了。

问题是，cassandra-driver-core的版本与cassandra版本不兼容。

Java连接到Cassandra NoHostAvailableException
