Xuan Gong commented on YARN-1157:
---------------------------------
The reason is: At RMAppAttemptImpl::generateProxyUriWithoutScheme(String)
{code}
return
result.toASCIIString().substring(HttpConfig.getSchemePrefix().length());
{code}
can return an empty String,
But at WebAppProxyServlet, it only check whether the urlString is null or not,
we should also check the empty string.

> Submit YARN distributed shell application. Goto ResourceManager Web UI. The

> link. Click on that link. Instead of showing application master web UI, HTTP
