Can not connect to any HDP UI on AWS

Can not connect to any HDP UI on AWS

New Contributor

Hi all,

After installing the HDP 2.6 on AWS, I can connect to the Amabri server and start all services but when I try to connect to any UI, for example Name node UI on 50070 using the public IP address I get a connection refused (ERR_CONNECTION_REFUSED).

I open all the port on my VM to be sure this is not an issue related to the VM accessibility.

On the VM, the netstat -anp | grep 50070:

tcp 0 0 127.0.0.1:60294 127.0.0.1:50070 TIME_WAIT -

tcp 0 0 127.0.0.1:60310 127.0.0.1:50070 TIME_WAIT -

tcp 0 0 127.0.0.1:50070 127.0.0.1:60613 ESTABLISHED 5369/java

tcp 0 0 127.0.0.1:50070 127.0.0.1:60612 ESTABLISHED 5369/java

tcp 0 0 127.0.0.1:50070 127.0.0.1:60646 TIME_WAIT -

tcp 0 0 127.0.0.1:60292 127.0.0.1:50070 TIME_WAIT -

My /etc/hosts:

127.0.0.1 ambariserver.com localhost localhost.localdomain localhost4 localhost4.localdomain4

And in the HDFS Namenode log:

STARTUP_MSG: host = ambariserver.com/127.0.0.1

Thanks for your help

I found a work around by adding a mapping between the Public IP and the hostname in the /etc/hosts.

But not a good solution as Public IP address change at each reboot!!
