> I frequently want to persist some RDDs to disk and choose the names of the files that they are saved as.
> Currently, the {{RDD.checkpoint}} flow [writes to a directory with a UUID in its name|https://github.com/apache/spark/blob/v1.5.1/core/src/main/scala/org/apache/spark/SparkContext.scala#L2050], and the file is [always named after the RDD's ID|https://github.com/apache/spark/blob/v1.5.1/core/src/main/scala/org/apache/spark/rdd/ReliableRDDCheckpointData.scala#L96].
> Is there any reason not to allow the user to e.g. pass a string to {{RDD.checkpoint}} that will set the location that the RDD is checkpointed to?
