Subject Gelly EOFException
Date Tue, 14 Jul 2015 12:06:45 GMT
Hi to all,

in my vertex centric iteration I get the following exception, am I doing
something wrong or is it a bug of Gelly?

starting iteration [1]:  CoGroup (Messaging) (6/8)
IterationHead(WorksetIteration (Vertex-centric iteration
(test.gelly.functions.VUpdateFunction@1814786f
| test.gelly.functions.VMessagingFunction@67eecbc2))) (4/8) switched to
FAILED with exception.
