> 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:
> {noformat}
> Connection jdbc = DriverManager.getConnection(this.con,"hive","password");
> "jdbc:hive2://localhost:10000/default",
> {noformat}
> The logs get to here before the hang :
> {noformat}
