> It can be confusing when authentication is turned on by default in a cluster, and one tries to start spark in local mode for a simple test.
> *Workaround*: If {{spark.authenticate=true}} is specified as a cluster wide config, then the following has to be added
> {{--conf "spark.authenticate=false" --conf "spark.shuffle.service.enabled=false" --conf "spark.dynamicAllocation.enabled=false" --conf "spark.network.crypto.enabled=false" --conf "spark.authenticate.enableSaslEncryption=false"}}
> in the spark-submit command.
