      Description

      I've noticed that when there is an underlying issue in connecting a client to the JDBC interface of the HiveServer2 to run queries, you get a hang after the thrift portion, at least in certain scenarios:

      Turning log4j to DEBUG, you can see the following when trying to get a connection using:

              Connection jdbc = DriverManager.getConnection(this.con,"hive","password");
              "jdbc:hive2://localhost:10000/default",
      

      The logs get to here before the hang :
