             Project: Hive
          Issue Type: Bug

Hi,

We are trying to use TypeInfoUtils to validate the data type information of a 
string.

map<array<int>,string> comes back as data type MAP . I was expecting this to 
give back error as map key should only be a primitive type.

Could you please check and let us know if this is already known issue or this 
is something that has to be fixed.

Thanks!

Mona
