I discovered several instances of discussion on leftFold and rightFold in a variety of forums, but I can not find anything related to RDD in the official documentation:
It appears to be non-related to Spark, and probably something Hadoop-related. Can you please be more specific on how leftFold and rightFold is imported and the language you are using to implement Spark?
Thanks!
