> This is related to YARN-3238. Ran into more scenarios where connection
> errors are being retried at multiple levels, like NoRouteToHostException.
> The fix for YARN-3238 was too specific, and I think we need a more general
> solution to catch a wider array of connection errors that can occur to avoid
> retrying them both at the RPC layer and at the NM proxy layer.
