Li Lu commented on YARN-3477:
-----------------------------

I just noticed this JIRA when going through the ticket list of YARN-5355. I 
believe this is some change that is useful to TimelineClient, but this patch no 
longer applies. [~ste...@apache.org] if you happen to have time, would you mind 
to rebase this patch? Thanks!

> If timeline client fails more than the retry count, the original exception is 
> not thrown. Instead some runtime exception is raised saying "retries run out"
> # the failing exception should be rethrown, ideally via 
> NetUtils.wrapException to include URL of the failing endpoing
> # Otherwise, the raised RTE should (a) state that URL and (b) set the 
> original fault as the inner cause
