![Hive [ 08S01] Could not open client transport with JDBC Uri: jdbc:hive2://hadoop102:10000: java.net](http://www.mshxw.com/aiimages/31/991839.png "Hive [ 08S01] Could not open client transport with JDBC Uri: jdbc:hive2://hadoop102:10000: java.net")
连接hive时出现了一个错误：
[ 08S01] Could not open client transport with JDBC Uri: jdbc:hive2://hadoop102:10000: java.net.ConnectException: Connection refused: connect
java.net.ConnectException: Connection refused: connect.
之前一直好好的，断了重新连接或者填写密码都不行，中间挂起了一次虚拟机。查询后发现可能是hiveserver2没有开启。
开启hiveserver2：
hive --service hiveserver2
重新测试。
可以了。
