Hiveserver2 – hive-jdbc version conflict

When I tested connecting hive by hiveserver2, I got error:

Exception in thread "main" java.sql.SQLException: Could not open client transport with JDBC Uri: jdbc:hive2://localhost:10000/test_hive: Could not establish connection to jdbc:hive2://localhost:10000/test_hive: Required field 'client_protocol' is unset!

After checking, it’s said that the version of hive-jdbc and hive are conflict, so I changed hive-jdbc version as the same as hive, problem solved.
