> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.4
> Reporter: weiwenda
> Priority: Minor
> Fix For: 3.1.0, 2.4.6

>
> # 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!
