Josh Rosen commented on SPARK-2855:
-----------------------------------
Do you recall the actual exception? Was it a Py4J error (something like
"connection to GatewayServer failed?"). It seems like we've been experiencing
some flakiness in these tests and I wonder whether it's due to some system
resource being exhausted, such as ephemeral ports.
