-------------------------------------
Hi,
I have this problem when I try to run SparkR shell and PySpark shell at the
same time. I don't understand why it tries to initialize the database twice?
Can we have singleton factory design pattern to order to ensure that the once
the database is initialized, it will always get the same instance? Since I am
just a newbie to Spark, what is the difficulty to have such code to avoid to
initialize database twice ?
Thank you
