- Load CDAP UI and go to Data Preparation
- Import some JSON data(have attached a sample json) and parse the column as json.
- When maximum depth level specified is 1 it should only parse the top level keys in the json and create new columns. Something like here: https://docs.cask.co/cdap/4.3.0/en/user-guide/data-preparation/directives/parse-as-json.html
- For some reason some keys at the top level, which contain objects, gets flattened to individual columns whereas some other keys with objects don't.
