> Further notes:
> 1. I experimented with removing the FOREACH...GENERATE statement where this error seems to be occurring. But then, I get the error message:
> ERROR 2270: Logical plan invalid state: duplicate uid in schema
> 2. When I ran the script with the argument-option `-t ColumnMapKeyPrune`, the script did successfully run albeit very slowly.
