I draw a simple graph to illustrate what's happened when set spark.sql.catalogImplementation to xsql, or calling SparkSession.builder().enableXSQLSupport() 

As long as you change spark.sql.catalogImplementation to xsql, both spark-hive-thriftserver and spark-repl will start to support multi-datasource instead of one hive only. For permanent change, add new line `spark.sql.catalogImplementation=xsql` in...

@wushengyeyouya do you want to use hive thriftserver2 jdbc？

How does Scriptis&Linkis use spark now? xsql usage is all the same as spark

You can configure spark.sql.catalogImplementation=xsql in spark-defaults.conf，so that spark-shell、spark-sql、spark-submit will enable XSQL syntax. But above configuration only works in `bin` version, spark.sql.catalogImplementation=xsql is not allowed in raw spark. 

I new a project to show how to create and test new customized datasource manager. Please download and see https://github.com/WeiWenda/mock-datasource-manager.git
