Hi Samza devs, I ran into an issue with Samza 0.9.1 where I had a serialization exception thrown in the MetricsSnapshotReporter. It's very hard to find because nothing is logged and the metrics just stop getting scheduled. Samza should catch all exceptions in that thread, log them, and suppress them rather than no longer scheduling snapshot metrics at all.
JIRA filed here: https://issues.apache.org/jira/browse/SAMZA-801 Cheers, Roger
