I am trying to create a dashboard from the data present in the Hive. The catch is the column which I want to visualize is a nested JSON type. So will tableau able to parse and flatten the JSON column and list out all possible attributes? thanks!
Unfortunately Tableau will not automatically flatten the JSON structure of the field for you, but you can manually do so.
Here is an article that explains the use of Regex within Tableau to extract pertinent information from your JSON field.
I realize this may not be the answer you were looking for, but hopefully, it gets you started down the right path.
(In case it helps, Tableau does have a JSON connector in the event you are able to connect directly to your JSON as a datasource instead of embedded in your Hive connection as a complex field type.)
