---------------------------------
> Is there any possible that spark no longer restrict enumerate types of
> spark.sql.catalogImplementation
> ------------------------------------------------------------------------------------------------------
>
> Key: SPARK-30617
> URL: https://issues.apache.org/jira/browse/SPARK-30617
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: weiwenda
> Priority: Minor
>
> # We have implemented a complex ExternalCatalog which is used for retrieving
> multi isomerism database's metadata(sush as elasticsearch、postgresql), so
> that we can make a mixture query between hive and our online data.
> # But as spark require that value of spark.sql.catalogImplementation must be
> one of in-memory/hive, we have to modify SparkSession and rebuild spark to
> make our project work.
> # Finally, we hope spark removing above restriction, so that it's will be
> much easier to let us keep pace with new spark version. Thanks!
