Was expected that the columns can be renamed during the creation of a Transformation feed or using the Visual Query, but it doesn't work.
The error can appear:
after renaming the column successfully, but during the schema preview (Step 5 table) - for a table with 2 columns
during the rename (Step 4 Transform Data) - for a table containing 50+ columns
The tables are from Hive
Attached are screenshots with the errors.
