Hyukjin Kwon resolved SPARK-15147.
----------------------------------
Resolution: Incomplete
> Catalog should have a property to indicate case-sensitivity
> -----------------------------------------------------------
>
> Key: SPARK-15147
> URL: https://issues.apache.org/jira/browse/SPARK-15147
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Cheng Lian
> Priority: Major
> Labels: bulk-closed
>
> We are moving from Hive metastore catalog to a more general extensible
> catalog design. One problem that hasn't been taken care of in current Spark
> 2.0 interfaces is case sensitivity. More specifically, Hive metastore is case
> insensitive. It simply stores column names, table names, struct field names,
> and function names in lower case, and thus isn't even case-preserving.
> However, case sensitivity in Spark SQL is configurable. We need to add
> property (or properties) to {{Catalog}} interface to indicate
> case-sensitivity of underlying catalog implementations.
