Debugging PySpark: Spark Summit East talk by Holden Karau 

You convinced me to learn Scala.

Hi, Holden, thank you for sharing this wonderful talk, I wonder if you can give more details about PySpark? You mentioned py4j, pickling, magic, what's that and how they behaive?

probably one the best videos on debugging pyspark applications.

Why does she have to bring up all the transgender stuff? I don't see other speakers bringing up their religious or political opinions in an engineering talk.

wow，why do i head a man voice? not a women voice.
