Unable to connect to Hive from Eclipse

Question

I'm new to Big Data/Hadoop. I'm trying to connect to Hive from Eclipse using JDBC. I keep getting the following error. I have no idea what's going on. Please help.

I would first try to login without using UserGroupInformation , you should be able to connect simply using the DriverManager.getConnection() , I do the same with an h2 database and it works fine. It sounds like it is an issue with the authentication process you are trying to use which I am not very familiar with.
