无法连接到直线 hive2

Question

Hadoop 2.7.3 和 Hive 2.1.0

我可以像这样连接到直线

!connect jdbc:hive2://

但是当我输入时

!connect jdbc:hive2://hostname:10000/default org.apache.hive.jdbc.HiveDriver 或 !connect jdbc:hive2://hostname:10000/default

给出用户名和密码后 它给了我一个错误

错误：无法打开与 jdbc:hive2://:10000 的连接：java.net.ConnectException：连接被拒绝 (state=08S01,code=0)

在 CLI 中：

有什么建议吗？

我为 hive 2 设置的 hive-site.xml 中的属性是：-

有什么建议吗？

Answer 1

1. 首先检查您的配置单元服务器是否正在侦听端口 10000？

   netstat -an | grep 10000

   如果没有！转到 /tmp/{username}/hive.log 看看有什么问题！

2. 如果 hive 服务器已启动并正在运行，请检查您创建的架构！

   schematool -validate -dbType -verbose

   如果架构有问题，那么您应该重新初始化架构。

3. 如果一切正常，那么您应该使用以下方式连接：

   beeline -u jdbc:hive2://{IP or servername}:10000

Answer 2

来自错误：

16/10/25 18:07:11 [main]: WARN jdbc.HiveConnection: Failed to connect to 10.1.1.60:1000
Error: Could not open client transport with JDBC Uri: jdbc:hive2://10.1.1.60:1000/;transportMode=binary: java.net.ConnectException: Connection refused (state=08S01,code=0)

看起来您正在访问端口 1000 而不是 10,000 - 如果您连接到端口 10000 是否有效？

如果它对端口 10000 仍然不起作用，您确定 Hiveserver2 正在侦听该端口吗？您能否在 Hiveserver2 主机上运行以下命令并确保端口上正在侦听某些内容：

netstat -an | grep 10000
