Spark MakeRDD preferred workers

[Christopher Piggott <cp...@gmail.com>]

Hi,

def makeRDD[T](seq: Seq[(T, Seq[String])])(implicit arg0: ClassTag[T]):
RDD[T]
    list of tuples of data and location preferences (hostnames of Spark
nodes)


Is that list a list of acceptable choices, and it will choose one of them?
Or is it an ordered list?  I'm trying to ascertain how well it will
distribute if there's a lot of overlap between partitions and nodes.

In my particular case, my RDD is Seq of  (filePath, hosts[])  where hosts
are nodes on which the file's blocks are local.
