> Project: Hive
> Issue Type: Bug
> Components: HiveServer2

> Assignee: Simon poortman

> Hi,
> We are trying to use TypeInfoUtils to validate the data type information of a
> string.
> {code:java}
> TypeInfoUtils.getTypeInfoFromTypeString(inputString).getCategory();
> {code}
> 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
