Robert Hou commented on DRILL-4692:
-----------------------------------
This query sometimes works correctly through the WebUI. Meaning sometimes it
displays the contents of the "user" column instead of displaying the name of
the user.
> Column named user unresolvable
> ------------------------------
>
> Key: DRILL-4692
> URL: https://issues.apache.org/jira/browse/DRILL-4692
> Project: Apache Drill
> Issue Type: Bug
> Components: Server
> Affects Versions: 1.6.0
> Reporter: John Omernik
> Priority: Major
>
> With a set of Parquet files created outside of drill is attempted to be
> processed in Drill, and that set of files contains a column named "user" it
> is impossible to resolve that column, as Drill always replaces user with the
> currently logged in user.
> select user from table -> the logged in user
> select `user` from table -> the logged in user
> There is just no way to address that field. Backticks should allow us to
> access that field.
