Gabriel Reid commented on CRUNCH-458:
-------------------------------------

I'm wondering if basing the comparator on something as simple as the toString() 
of the NodePath and PCollectionImpl would be good enough (but using the real 
equals to determine equality). In a way that seems too naive to work, but on 
the other hand I can't see any immediate reason why it wouldn't work.

> I'm running into a pipeline in which the decision of where to split two 
> dependent jobs seems to be random from run-to-run (I only noticed it b/c one 
> of the runs causes the pipeline to throw an NPE, and the other does not.) I'd 
> like to investigate this and try to eliminate any potential sources of 
> randomness in the way that two dependent GBK operations are split.
