I made sure that using Teradata Studio 15.10 I can connect to Cloudera Hadoop even though in this version the only option is Hadoop Hortonworks.
I can't understand why I can't connect by Teradata Estudio 16 when I select Cloudera option.
I'm not sure about what you want I show you.
Depend on your needs, I could put you on touch with the SA of the account. May be he can give you more technical information.
