Question

我正在使用javax.sql.DataSource创建与hive的jdbc连接，并将zookeeper服务发现（从Ambari获取）字符串传递给Hive。

Zookeeper Hive URL : jdbc:hive2://localhost:2181/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2;transportMode=http;httpPath=cliservice

如果我与HiveServer主机和端口建立直接的jdbc连接，那么连接正常工作但是它与zookeeper字符串失败。

之后我用直线测试了zookeeper字符串，我工作得很好。

以下是连接时的例外情况。

有没有人遇到过这个？

花了我2天后，我发现了问题。我在我的代码中发生了这个问题的hive 0.14依赖。要修复我在下面更新的两个hive maven依赖项..

Hive服务 - https://mvnrepository.com/artifact/org.apache.hive/hive-service/1.2.1000.2.4.2.10-1

Hive JDBC - https://mvnrepository.com/artifact/org.apache.hive/hive-jdbc/1.2.1000.2.4.2.10-1

无法通过JDBC将Hive与Zookeeper服务发现模式连接
