> Currently,  in the run method in SamzaContainer.scala, we catch only Exceptions and re-throw them. 
> However, when there's an Error (like for example - a MethodNotFound Error owing to say - a backward incompatible change in one of the binaries used by the user-code) thrown from inside, it is not logged or caught. Consequently, there's no information or logs for that error and it goes mysteriously missing.
> Fix:
> We must add a catch for Throwables (to make it more general) and throw a SamzaException wrapping the Throwable as the cause.
