java - 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://

但是当我打字的时候

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

输入用户名和密码后它给我一个错误

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:

which: no hbase in (/user/local/maven/bin:/user/local/maven/bin:/user/local/maven/bin:/user/local/maven/bin:/user/local/maven/bin:/usr/local/rvm/gems/ruby-2.1.2/bin:/usr/local/rvm/gems/ruby-2.1.2@global/bin:/usr/local/rvm/rubies/ruby-2.1.2/bin:/usr/lib64/qt-3.3/bin:/user/local/maven/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/rvm/bin:/usr/local/hive/bin:/usr/bin:/usr/local/bin:/bin:/root/bin:/usr/java/jdk1.7.0_60/bin:/usr/local/hadoop/bin/:/usr/local/hadoop/bin:/usr/local/hadoop/sbin:/usr/bin:/usr/local/bin:/usr/java/jdk1.7.0_60/bin:/usr/java/jdk1.7.0_60/bin:/usr/local/hadoop/bin/:/usr/local/hadoop/bin:/usr/local/hadoop/sbin:/usr/bin:/usr/local/bin:/usr/java/jdk1.7.0_60/bin:/usr/java/jdk1.7.0_60/bin:/usr/local/hadoop/bin/:/usr/local/hadoop/bin:/usr/local/hadoop/sbin)

有什么建议吗？？

我为配置单元 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 Hive 服务器是否正在监听端口 10000？

   网络统计-an | grep 10000

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

2. 如果配置单元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 或服务器名}:10000
