various issues with running yarn proxyserver

    Details

      Description

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

      1. 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
      1. Setting yarn.web-proxy.address and running the service results in the following:
      $ ./sbin/yarn-daemon.sh start proxyserver 
      starting proxyserver, logging to /tmp/hadoop-0.23.1/logs/yarn-rvs-proxyserver-ahmed-laptop.out
