Steve Loughran commented on YARN-3477:
--------------------------------------
It would have really nice if this patch could have been reviewed and committed
when it actually compiled against the code
as it is, it'll be a significant piece of work to try and merge in. I don't
have the time this week, and am off on vacation from friday.
Can you look at the core changes: the exception logging, wrapping,
{{nterruptedIOException}} rethrowing, and replicate that in your ongoing work?
That's all that matters.
I'll watch your JIRA and review it.

> 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
