"Re: About Rapidminer Studio using Radoop - Hive problem"
Do you use the same Username and Password in the SQL Settings part of the connection dialog as you use in Beeline?
That username is usually hive, except when you are using LDAP or Kerberos, for example.
(You can check the JDBC URL that Radoop builds, if you enable the Log panel via View -> Show Panel -> Log, and set the log level to FINE (right click on the panel -> Set log level -> FINE) and run a test. You should see a line saying "Connecting to Hive. JDBC url:". You can ignore the radoop_hive_0.13.0 prefix, the rest should look similar to the URL that you use in Beeline.)
