Sean Owen commented on SPARK-650:
---------------------------------
This is still easy to do with mapPartitions, which can call
{{initWithTheseParamsIfNotAlreadyInitialized(...)}} once per partition, which
should guarantee it happens once per JVM before anything else proceeds. I don't
think you need to bury it in serialization logic. I can see there are hard ways
to implement this, but I believe an easy way is still readily available within
the existing API mechanisms.
