> Always Case Insensitive in HiveSessionState
> -------------------------------------------
>
> Key: SPARK-15217
> URL: https://issues.apache.org/jira/browse/SPARK-15217
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Xiao Li
> Priority: Blocker
>
> In a `HiveSessionState`, which is a given `SparkSession` backed by Hive, the
> analysis should not be case sensitive because the underlying Hive Metastore
> is case insensitive.
> For example,
> {noformat}
> CREATE TABLE tab1 (C1 int);
> SELECT C1 FROM tab1
> {noformat}
> In the current implementation, we will get the following error because the
> column name is always stored in lower case.
> {noformat}
> cannot resolve '`C1`' given input columns: [c1]; line 1 pos 7
> org.apache.spark.sql.AnalysisException: cannot resolve '`C1`' given input
> columns: [c1]; line 1 pos 7
> {noformat}
