> pyspark's accumulator server expects a secure py4j connection between python
> and the jvm. Spark will normally create a secure connection, but there is a
> public api which allows you to pass in your own py4j connection. (this is
> used by zeppelin, at least.) When this happens, you get an error like:
> {noformat}
> pyspark/accumulators.py: "TypeError: object of type 'NoneType' has no len()"
> in authenticate_and_accum_updates()
> {noformat}
> We should change pyspark to
> 1) warn loudly if a user passes in an insecure connection
> 1a) I'd like to suggest that we even error out, unless the user actively
> opts-in with a config like "spark.python.allowInsecurePy4j=true"
> 2) The accumulator server should be changed to allow insecure connections.
> note that SPARK-26349 will disallow insecure connections completely in 3.0.
