> Convert Keyword `path` of Data Source Tables to Lower Case
> ----------------------------------------------------------
>
> Key: SPARK-16999
> URL: https://issues.apache.org/jira/browse/SPARK-16999
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Xiao Li
>
> `path` points to the location of data source tables. The parameters' keywords
> are case insensitive. However, we do not always follow the rules. Below is
> the summary of the case sensitivity support:
> **Case sensitive**
> - AlterTableSetLocationCommand
> - AlterTableRenameCommand
> - TruncateTableCommand
> - newHadoopConfWithOptions in SessionState
> **Case insensitive**
> - ShowCreateTableCommand
> - CreateDataSourceTableCommand
> - CreateDataSourceTableAsSelectCommand
> - getBatch in FileStreamSource
> - write in DataSource
> - inferFileFormatSchema in DataSource
> - sourceSchema in DataSource
> - createSource in DataSource
> - createSink in DataSource
> - resolveRelation in DataSource
> It is not maintainable to consider the case sensitivity of `path` in all the
> current and future implementation. We should convert it to lower case for
> simplifying the handling.
