various issues with running yarn proxyserver
--------------------------------------------

                 Key: MAPREDUCE-3916
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3916
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2, resourcemanager, webapps
    Affects Versions: 0.23.1
            Reporter: Roman Shaposhnik


Seem like yarn proxyserver is not operational when running out of the 0.23.1 RC2 tarball.

# Setting yarn.web-proxy.address to match yarn.resourcemanager.address doesn't disable the proxyserver (althought not setting yarn.web-proxy.address at all correctly disable it and produces a message: org.apache.hadoop.yarn.YarnException: yarn.web-proxy.address is not set so the proxy will not run). This contradicts the documentation provided for yarn.web-proxy.address in yarn-default.xml

# Setting yarn.web-proxy.address and running the service results in the following:
