Hanifi Gunes commented on DRILL-1311:

A simple test seems to work. Should be fixed by DRILL-1324.

> - 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.
