連接到Cassandra數據庫並創建密鑰空間時出現以下錯誤。沒有足夠的可讀字節數 - 需要4，最大值爲0
異常線程 「main」> com.datastax.driver.core.exceptions.NoHostAvailableException：
所有主機（S）試了查詢失敗（嘗試：/127.0.0.1:9042
（COM。 datastax.driver.core.ConnectionException：[/127.0.0.1:9042]傳輸初始化期間出現意外錯誤
（com.datastax.driver.core.TransportException：[/127.0.0.1:9042]意外的異常觸發（java.lang。 IndexOutOfBoundsException：沒有足夠的可讀字節 - 需要4，最大值爲0）））
This i我的代碼：
package com.hadoop.reloaded.cassandra;
import com.datastax.driver.core.*;
public class CassandraOne {
public static void main(String[] args){
Cluster cluster1 = Cluster.builder().withPort(9042).addContactPoint("127.0.0.1").build();
Session session = cluster1.connect();
String query = "CREATE KEYSPACE test WITH replication "
+ "= {'class':'SimpleStrategy', 'replication_factor':1}; ";
session.execute(query);
session.execute("USE test");
}
}
，當我運行此異常拋出：
Exception in thread "main" com.datastax.driver.core.exceptions.NoHostAvailableException:
All host(s) tried for query failed (tried: /127.0.0.1:9042 (

您正在使用什麼版本的datastax java驅動程序，以及哪個版本的Cassandra？ –
我正在使用Java 1.8和Cassansdra 3.7版本 – AnYa
