> Pyspark normally produces a secure py4j connection between python & the jvm, but it also lets users provide their own connection.  Spark should fail fast if that connection is insecure.
> Note this is breaking a public api, which is why this is targeted at 3.0.0.  SPARK-26019 is about adding a warning, but still allowing the old behavior to work, in 2.x
