Multiple SparkSessions in single JVM

Question

I have a query regarding creating multiple spark sessions in one JVM. I have read that creating multiple contexts is not recommended in earlier versions of Spark. Is it true wit

Answer 1

You can call getOrCreate multiple times.

This function may be used to get or instantiate a SparkContext and register it as a singleton object. Because we can only have one active SparkContext per JVM, this is useful when applications may wish to share a SparkContext.

getOrCreate creates a SparkContext in JVM if there is no SparkContext available . If SparkContext is already available in JVM it doesn't creates a new but returns the old one.
