Varun Saxena updated HADOOP-12052:
----------------------------------
Attachment: HADOOP-12052.01.patch
> IPC client downgrades all exception types to IOE, breaks callers trying to
> use them
> -----------------------------------------------------------------------------------
>
> Key: HADOOP-12052
> URL: https://issues.apache.org/jira/browse/HADOOP-12052
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Steve Loughran
> Assignee: Brahma Reddy Battula
> Priority: Critical
> Fix For: 2.8.0
>
>
> 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.
