[jira] [Created] (DRILL-2033) JSON 'All Text mode' should support schema change from scalar to complex types

Neeraja created DRILL-2033:
------------------------------

             Summary: JSON 'All Text mode' should support schema change from scalar to complex types
                 Key: DRILL-2033
                 URL: https://issues.apache.org/jira/browse/DRILL-2033
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Neeraja


A scalar/simple field turning to complex field is a very common scenario in many JSON documents.
For ex: An integer turning into an array of integers , a string turning into a map of multiple strings .

Drill currently already provides ability to query the scalar data with datatype changes by turning all text mode to true.
This should be expanded it to support querying the scalar-complex type changes as well. This gives power for the users to look at the data without fixing/modifying JSON upfront.
