RDD from partitions

[Jem Tucker]

Hi,

I am trying to create an RDD from a selected number of its parents
partitions. My current approach is to create my own SelectedPartitionRDD
and implement compute and numPartitions myself, problem is the compute
method is marked as @developerApi, and hence unsuitable for me to be using
in my application. Are there any alternative methods that will only use the
stable parts of the spark API?

Thanks,

Jem
