      Description

      • Create a directory with a couple of JSON files. One with columns a,b and second with columns a,b,c.
      • a & b attributes have same data types across both the files
      • create a view by selecting columns a, b from the directory
      • Join the view with any other table

      An error shows up indicating that 'Hash join does not support schema changes'.
      There is a schema change across the files with a new element being added, however given that specific columns a,b are selected in the view, expect that query works fine.
