> Reporter: Steve Loughran
> Assignee: Brahma Reddy Battula
> Priority: Critical

>
> The HADOOP-11772 cache changes mean that an exception such as
> {{UnknownHostException}} being raised on a Client connect is now being
> returned as a simple {{IOException}}, wrapping an {{ExecutionException}},
> with the real exception being hidden inside that.
> This breaks any application which uses the exception class in a try/catch
> statement so as to choose different actions depending on the failure mode.
> This has surfaced in the SLIDER-896 tests, but is likely to happen in
> production too.
