Calling cache/persist fails all our jobs (i have posted 2 threads on this).
And we're giving up hope in finding a solution.
So I'd like to find a workaround for that:
If I save an RDD to hdfs and read it back, can I use it in more than one operation?
Example: (using cache)
// do a whole bunch of transformations on an RDD
val result1 = myrdd.map(op1(_))
val result2 = myrdd.map(op2(_))
// in the above I am assuming that a call to cache will prevent all previous transformation from being calculated twice
I'd like to somehow get result1 and result2 without duplicating work. How can I do that?
