an RDD cannot contain elements of type RDD. (i.e. you can't nest RDDs within RDDs, in fact, I don't think it makes any sense)
I suggest rather than having an RDD of file names, collect those file name strings back on to the driver as a Scala array of file names, and then from there, make an array of RDDs from which you can fold over them and merge them. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/How-to-merge-a-RDD-of-RDDs-into-one-uber-RDD-tp20986p21007.html Sent from the Apache Spark User List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
