Hi,   I am trying to install development instance of Hadoop on Microsoft Azure VM (A single node cluster).  I am running Ubuntu 12.04.3 LTS Linux.   Everything is going well until the very last step in the installation process where I get the following -    Installation failed. Failed to receive heartbeat from agent. Ensure that the host's hostname is configured properly. Ensure that port 7182 is accessible on the Cloudera Manager server (check firewall rules). Ensure that ports 9000 and 9001 are free on the host being added. Check agent logs in /var/log/cloudera-scm-agent/ on the host being added (some of the logs can be found in the installation details). I looked at the logs and see the following errors -   >>[19/Nov/2013 15:00:55 +0000] 1922 MainThread agent INFO Re-using pre-existing directory: /run/cloudera-scm-agent/process  >>[19/Nov/2013 15:00:55 +0000] 1922 MainThread agent INFO Re-using pre-existing directory: /run/cloudera-scm-agent/supervisor  >>[19/Nov/2013 15:00:55 +0000] 1922 MainThread agent INFO Re-using pre-existing directory: /run/cloudera-scm-agent/supervisor/include  >>[19/Nov/2013 15:00:55 +0000] 1922 MainThread agent INFO Connecting to previous supervisor: agent-1304-1384872987.  >>[19/Nov/2013 15:00:55 +0000] 1922 MainThread _cplogging INFO [19/Nov/2013:15:00:55] ENGINE Bus STARTING  >>[19/Nov/2013 15:00:55 +0000] 1922 MainThread _cplogging INFO [19/Nov/2013:15:00:55] ENGINE Started monitor thread '_TimeoutMonitor'.  >>[19/Nov/2013 15:00:55 +0000] 1922 HTTPServer Thread-2 _cplogging ERROR [19/Nov/2013:15:00:55] ENGINE Error in HTTP server: shutting down  >>Traceback (most recent call last):  >> File "/usr/lib/cmf/agent/build/env/lib/python2.7/site-packages/CherryPy-3.2.2-py2.7.egg/cherrypy/process/servers.py", line 187, in _start_http_thread  >> self.httpserver.start()  >> File "/usr/lib/cmf/agent/build/env/lib/python2.7/site-packages/CherryPy-3.2.2-py2.7.egg/cherrypy/wsgiserver/wsgiserver2.py", line 1825, in start  >> raise socket.error(msg)  >>error: No socket could be created on ('NexusHadoopVM', 9000) -- [Errno 99] Cannot assign requested address  >>  >>[19/Nov/2013 15:00:55 +0000] 19   I checked if anything is already using 9000 and 9001 via lsof -i :9000  lsof -i :9001 as well as netstat and both came with nothing.  In the Azure VM manager I specified that both 9001 and 9002 are open (private and public), not sure what else needs to be configured.   I also using public IP address when adding a node to the cluster.   Please help!!! ...
