unable to get driver instance: jdbc:hive2://172.16.26.218:10000

Hive连接报错：
Could not open client transport with JDBC Uri: jdbc:hive2://192.168.216.128:10000: java.net.ConnectException: Connection refused: connect
java.net.ConnectException: Connection refused: connect
java.net.ConnectException: Connection refused: connect
Connection refused: connect
Connection refused: connect

解决方法：查看hiveserver2是否启动成功，查看10000端口

[root@bigdata1 lib]# netstat -anp|grep 10000
1

没有输出，确定是hiveserver2没有启动成功。

启动hiveserver2
如下所示，hiveserver2会启动几个Hive Session ID

[root@bigdata1 bin]# /moudle/hive-3.1.2/bin/hiveserver
