Chris Riccomini commented on SAMZA-178:
---------------------------------------
Agreed. We should change all of these guys to Exception. I have seen Samza
tasks hang with OOMEs because we're catching them. This is not good.
> Review catching of Throwable
> ----------------------------
>
> Key: SAMZA-178
> URL: https://issues.apache.org/jira/browse/SAMZA-178
> Project: Samza
> Issue Type: Task
> Reporter: Martin Kleppmann
>
> We have various places in the code where we do:
> {noformat}
> try { ... } catch { case _ => ... }
> try { ... } catch { case e: Throwable => ... }
> {noformat}
> That's potentially dangerous, because Throwable is the supertype for various
> things that really shouldn't be caught by normal code, such as
> java.lang.OutOfMemoryError or scala.runtime.NonLocalReturnControl (the latter
> is used internally by Scala for flow control).
> We should probably change most or all of those occurrences to catch Exception
> instead. But it's worth reviewing each case to make sure that it really
> doesn't need to catch Throwable after all.
> See also discussion on https://reviews.apache.org/r/18606/ (SAMZA-161).
