> Sometimes when an error occurs it may be helpful to have operator stack with 
> context data along with original stacktrace to help developers to track down 
> a failure. To achieve this, each operator should provide a context which can 
> be dumped to logs. In the end of FragmentExecutor's execution if the state is 
> FAILED the operator stack will be dumped to logs before exception stacktrace.
