The expected outcome of rename directive of dataprep doesn't seem to be intuitive.
Steps to reproduce,
1. Upload a data and generate a data table with 5 column schema, say C1, C2, C3, C4, C5.
2. Now rename C2 to C4.
3. Rename C5 to C1
- C2 should overwrite C4 and contents of C2 should prevail
- C5 should overwrite C1 and contents of C5 should prevail
The opposite happens. C2 gets overwritten and contents of C4 prevails.
