beeline连接hiveserver2 踩坑2小时!!

beeline连接hiveserver2的经历

  • 首先安装好hive之后启动hiveserver2服务
[hadoop@localhost apache-hive-2.3.6-bin]$ hiveserver2 
which: no hbase in (/home/hadoop/app/jdk1.8.0_201/bin:/home/hadoop/app/jdk1.8.0_201/jre/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/hadoop/.local/bin:/home/hadoop/bin:/home/hadoop/app/apache-hive-2.3.6-bin/bin:/home/hadoop/app/hadoop-2.8.5/bin:/home/hadoop/app/hadoop-2.8.5/sbin:/home/hadoop/.local/bin:/home/hadoop/bin)
2020-02-27 05:16:25: Starting HiveServer2

  • 开启另外一个窗口
[hadoop@hadoop101 hadoop]$ beeline -u jdbc:hive2://localhost:10000 -n hadoop

报错!!!

  • 检查报错
Please check the server URI and if the URI is correct, then ask the administrator to check the server status

这里的意思就是说使用jdbc连接mysql的URI出了问题,这时候就需要去hive-site.xml上检查一下是否写错!

  • hive.site.xml
<property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://localhost:3306/metastore?createDatabaseIfNotExist=true&userSSL=false</value>
    <description>the URL of the MySQL database</description>
  </property>

发现问题 “?userSSL=false” 这个写法是有问题的 需要改写成:

<property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://localhost:3306/metastore?createDatabaseIfNotExist=true&amp;useSSL=false</value>
    <description>the URL of the MySQL database</description>
  </property>

为什么要添加userSSL呢是因为使用mysql版本是5.7+的所以需要添加。

  • 最后使用beeline连接
[hadoop@hadoop101 hadoop]$ beeline -u jdbc:hive2://localhost:10000 -n hadoop

成功!!!
