Cheng Lian commented on SPARK-6397:
-----------------------------------
Hey [~smolav], after some discussion with [~waterman] in his PRs, we decided to
fix the GROUPING__ID virtual column issue first. So I updated the title and
description of this JIRA ticket, and created SPARK-6467 for the original one.
You may link your PR to that one. Thanks! I should have created another JIRA
ticket for the fix introduced in [~waterman]'s PR, but I realized the problem
too late after merging it.
