No WebUIs are working except for Cloudera Manager

No WebUIs are working except for Cloudera Manager

Explorer

Hi,

   I have a cloudera cluster installed - it is CDH 5.5.2.  All of the services look fine - everything is green!  All of the hosts have green dots, and the services too when I drill down on any service. 

 

I can create a spark job, do spark-submit and run the job, I can put stuff into hdfs and retrieve it from hdfs.  For some reason no Web UIs work outside of Cloudera Manager. hue, Yarn Manager, Spark History Server, Solr, all the UIs just don't even get resolved.  I can go to the Apache2 Ubuntu home page on port 80 as well. 

 

Any ideas at all would help at this point.

The problem was ports.  I did not have all of the ports open on my cluster.

How did you solve your problem? my 50070 door doesn't appear after a 

netstat -tulpn

command, so I have problems all around Cloudera. Restarting the namenode didn't solve it, neither did putting a rule exception in the iptables file:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
