我刚刚下载了HDP-Sandbox（在Oracle VirtualBox VM中），从未使用太多，现在我正在尝试使用Hive HDBC从外部访问数据。
我使用apache中的hive-jdbc 1.2.2，我从mvnrepository获取，包含类路径中的所有依赖项，或者hortonworks JDBC从其存储库中获取
http://mvnrepository.com/artifact/org.apache.hive/hive-jdbc/1.2.2
或
http://repo.hortonworks.com/content/repositories/releases/org/apache/hive/hive-jdbc/1.2.1000.2.6.4.0-91
我写了这个非常基本的程序
import java.sql.Connection;
import java.sql.DriverManager;
public class Main {
public static void main(final String[] args) {
try {
final Class<?> driver = Class.forName("org.apache.hive.jdbc.HiveDriver");
DriverManager.setLoginTimeout(10);
try (final Connection connection = DriverManager.getConnection("jdbc:hive2://sandbox.hortonworks.com:2181/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2")) {
//
}
} catch (final Exception e) {
e.printStackTrace();
}
}
}
连接失败，出现Null指针异常或超时（请参阅下面的输出日志，我使用的每个JDBC驱动程序都有一个），我猜这是由配置错误引起的 - 即使我使用我的沙箱出了...框。

好吧，我无法解决这个问题。
但是后来，我下载了2.6.4沙盒，魔术，它就像一个魅力！
