-------------------------------------
Resolution: Duplicate
> Credentials readTokenStorageFile to stop wrapping IOEs in IOEs
> --------------------------------------------------------------
>
> Key: HADOOP-14789
> URL: https://issues.apache.org/jira/browse/HADOOP-14789
> Project: Hadoop Common
> Issue Type: Improvement
> Components: security
> Affects Versions: 2.8.1
> Reporter: Steve Loughran
> Priority: Minor
>
> When {{Credentials readTokenStorageFile}} gets an IOE. it catches & wraps
> with the filename, so losing the exception class information.
> Is this needed. or can it pass everything up?
> If it is needed, well, it's a common pattern: wrapping the exception with the
> path & operation. Maybe it's time to add an IOE version of
> {{NetworkUtils.wrapException()}} which handles the broader set of IOEs
