Istvan Toth reassigned PHOENIX-6668:
------------------------------------
Assignee: Istvan Toth
> Spark3 connector cannot distinguish column name cases
> -----------------------------------------------------
>
> Key: PHOENIX-6668
> URL: https://issues.apache.org/jira/browse/PHOENIX-6668
> Project: Phoenix
> Issue Type: Bug
> Reporter: Istvan Toth
> Assignee: Istvan Toth
> Priority: Major
>
> The Spark2 connector handled lowercase and mixed case column names correctly
> in DataFrame definitions.
> Spark3 only does case-insensitive column resolving, and even
> _spark.sql.caseSensitive_ doesn't seem to do anything, neither backquouting.
> Again, this is not something that can likely be fixes from the Phoenix side
> without changes in Spark, and this ticket is mainy for documenting this
> regression.
