-----------------------------------

bq. since the originalTrackingUrl is set to "N/A" 

There's a related bug that we've seen before. Since originalTrackingUrl is set to "N/A" when
registration and unregistration doesn't supply a tracking url. When generating proxiedTrackingUrl,
generateProxyUriWithScheme is called with "N/A" as input

{code}
      final String scheme = WebAppUtils.getHttpSchemePrefix(conf);
      URI trackingUri = StringUtils.isEmpty(trackingUriWithoutScheme) ? null :
        ProxyUriUtils.getUriFromAMUrl(scheme, trackingUriWithoutScheme);
      String proxy = WebAppUtils.getProxyHostAndPort(conf);
      URI proxyUri = ProxyUriUtils.getUriFromAMUrl(scheme, proxy);
      URI result = ProxyUriUtils.getProxyUri(trackingUri, proxyUri,
          applicationAttemptId.getApplicationId());
{code}

Int generateProxyUriWithScheme, trackingUri will be set to "http://N/A", and result will be
set to a wrong string, such as "http://proxy.net:8080/proxy/application_1234567_0001/*A*".

> It would be nice if the Resourcemanager set the tracking url to the RM app page if the
application master doesn't pass one or passes the empty string.
