Resolution: Later
> Systematically catch exceptions
> -------------------------------
>
> Key: IMPALA-4663
> URL: https://issues.apache.org/jira/browse/IMPALA-4663
> Project: IMPALA
> Issue Type: Task
> Components: Backend
> Affects Versions: Impala 2.8.0
> Reporter: Jim Apple
> Priority: Major
>
> IMPALA-4498 showed a case where catching exceptions could have provided a
> mroe graceful exit. Unfortunately, both Boost and the C++ standard library
> use exceptions for error handling while Impala uses things like Status.
> We should audit the code for places where uncaught exceptions may occur and
> wrap them with {{try ... catch}} when appropriate.
> It would be nice if there were some static analysis tooling to help with
> this, but I'm not sure any such thing exists at the moment. It may be that
> the best possible would be line-by-line (or method-by-method) audit, which
> could be very time-consuming.
