When 0 is provided as port number in yarn.nodemanager.webapp.address, NMs webserver component picks up random port, NM keeps on Reporting 0 port ot RM
------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-3532
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3532
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 0.23.1
            Reporter: Karam Singh


I tried following -:
yarn.nodemanager.address=0.0.0.0:0
yarn.nodemanager.webapp.address=0.0.0.0:0
yarn.nodemanager.localizer.address=0.0.0.0:0
mapreduce.shuffle.port=0

When 0 is provided as number in yarn.nodemanager.webapp.address. 
NM instantiate WebServer as 0 piort e.g.
{code}
2011-12-08 11:33:02,467 INFO org.apache.hadoop.yarn.server.nodemanager.webapp.WebServer: Instantiating NMWebApp at 0.0.0.0:0
{code}

After that WebServer pick up some random port e.g.
{code}
2011-12-08 11:33:02,562 INFO org.apache.hadoop.http.HttpServer: Jetty bound to port 36272
2011-12-08 11:33:02,562 INFO org.mortbay.log: jetty-6.1.26
2011-12-08 11:33:02,831 INFO org.mortbay.log: Started SelectChannelConnector@0.0.0.0:36272
2011-12-08 11:33:02,831 INFO org.apache.hadoop.yarn.webapp.WebApps: Web app /node started at 36272
{code}

And NM WebServer responds correctly but
 RM's cluster/Nodes page shows the following -:
{code}
/Rack RUNNING NM:57963 NM:0 Healthy 8-Dec-2011 11:33:01 Healthy 8 12 GB 0 KB

Whereas NM:0 is not clickable.
Seems even NM's webserver pick random port but it never gets updated and so NM report 0 as HTTP port to RM causing NM Hyperlinks un-clickable
But verified that MR job runs successfully with random.
