> Support data source name mapping configuration
> ----------------------------------------------
>
> Key: SPARK-25143
> URL: https://issues.apache.org/jira/browse/SPARK-25143
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Dongjoon Hyun
> Priority: Major
>
> Currently, for better UX, Apache Spark provides data source backward
> compatibility by using the pre-defined built-in `backwardCompatibilityMap`.
> *
> [https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/DataSource.scala#L564]
> Although this mapping table is maintained carefully, but it's not flexible
> when we have multiple implementations like Avro/CSV/ORC.
> This issue aims to extend Spark backward-compatibility-mapping capability by
> allowing users provide a custom mapping in a general manner as configuration.
> If a user faces some issue with the provided mapping, he/she can override it
> by configuration.
