> I.e. the Hadoop RDD should look up the entire function for the computing
thread at the beginning, then it can invoke that function within the hot loop
only.
Commented inline above, but am I missing something about my implementation?
This is what I (thought) my code is doing. Unless you mean that looking up
the function per-task is too expensive?
