Li Lu commented on YARN-3477:
-----------------------------
Hi [[email protected]], thanks for the patch! The fixes on the timeline retry
logic looks good to me. BTW, I agree with [~zjshen] that we may want to change
some retry information's log level into debug. I used info level, but then
found this may generate some noise in a log with retries.

> 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
