GraphX, Kryo and BoundedPriorityQueue?

[Ryan Compton <co...@gmail.com>]

For me, PageRank fails when I use Kryo (works fine if I don't). I
found the same problem reported here:
https://groups.google.com/forum/#!topic/spark-users/unngi3JdRk8 .

Has this been resolved?

I'm not launching code from spark-shell. I tried registering
GraphKryoRegistrator (instead of my own classes), I still get the
below error:
