Abstract Value Members

abstract def getOrCreate(): Session

Gets an existing SparkSessionAPI or, if there is no existing one, creates a new one based on the options set in this builder.
Gets an existing SparkSessionAPI 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 config options specified in this builder will be applied to the existing SparkSession.
