Gets an existing SparkSession or, if there is no existing one, creates a new one based on the options set in this builder.
Gets an existing SparkSession or, if there is no existing one, creates a new one based on the options set in this builder.
This method first checks whether there is a valid thread-local SparkSession, and if yes, return that one. It then checks whether there is a valid global default SparkSession, and if yes, return that one. If no valid global default SparkSession exists, the method creates a new SparkSession and assigns the newly created SparkSession as the global default.
In case an existing SparkSession is returned, the non-static config options specified in this builder will be applied to the existing SparkSession.
