> When I run the job history server locally, every page load takes in the 10s
> of seconds. I profiled the process and discovered that all the extra time
> was spent inside YarnConfiguration#getRMWebAppURL, trying to resolve 0.0.0.0
> to a hostname. When I changed my yarn.resourcemanager.address to localhost,
> the page load times decreased drastically.
> There's no that we need to perform this resolution on every page load.
