Subject SyncException running hama job
Date Mon, 17 Feb 2014 06:18:05 GMT
Hi,

I get a SyncException when running my hama graph job. The stack trace shows
no reference to my own classes, so I have no idea why this is happening. It
runs fine when there's only one iteration (job.setMaxIteration(1)), though.
Sorry for the long trace:
