Hiveserver has been replaced by hiveserver2. For more information, please see:

Https://cwiki.apache.org/confluence/display/Hive/HiveServer

You can use the $HIVE_HOME/bin/hiveserver2 or $HIVE_HOME/bin/hive-- service hiveserver2 command to start HiveServer2

There are two differences between hiveserver and hiveserver2 in using JDBC connections:

1. Driver class: org.apache.hadoop.hive.jdbc.HiveDriver-- > org.apache.hive.jdbc.HiveDriver

2.URL:jdbc:hive://localhost:10000/default-- > jdbc:hive2://localhost:10000/default

In addition, when using hive jdbc, you need to import hive's jdbc driver package. If you use Maven, add dependencies.

Org.apache.hive

Hive-jdbc

1.2.0
