Hi spark users and developers,
Is it possible to disable HiveContext from being instantiated when using
spark-shell? I got the following errors when I have more than one session
starts. Since I don't use HiveContext, it would be great if I can have more
than 1 spark-shell start at the same time.
Exception in thread "main" java.lang.RuntimeException:
java.lang.RuntimeException: Unable to instantiate
