Vinod Kumar Vavilapalli commented on YARN-5080:
-----------------------------------------------
bq. Vinod Kumar Vavilapalli, the Jenkins test was actually kicked off but
failed to post here: https://builds.apache.org/job/PreCommit-YARN-Build/11442/
(test failures are not related and get tracked in YARN-4982). The same thing
keep happening during the same time for other JIRAs like YARN-4325, etc., so I
didn't mention it before in my previous review.
Ah, I see. That's okay, but next time please do a leave a comment on the main
JIRA so that others can also know what exactly happened.
bq. About the patch, I think you are right that we missed the case for
different RM bind-host configuration "yarn.resourcemanager.bind-host". However,
the existing WebAppUtils.getWebAppBindURL() seems doesn't handle well when
bind-host is set to "0.0.0.0".
I don't think that's the main bug. In the previous code,
{code}
String webAppAddress =
WebAppUtils.getWebAppBindURL(conf, YarnConfiguration.RM_BIND_HOST,
WebAppUtils.getRMWebAppURLWithScheme(conf));
{code}
you were passing a URL with scheme, whereas {{getWebAppBindURL()}} explicitly
needs a {{webAppURLWithoutScheme}} as parameter.
