I am having a problem with Ambari.
I am trying to use Ambari to install Hadoop to a three node cluster. the name node is where the Ambari server is located. I am getting this error:
ERROR 2014-12-12 17:39:56,963 main.py:137 – Ambari agent machine hostname (localhost.localdomain) does not match expected ambari server hostname (namenode). Aborting registration. Please check hostname, hostname -f and /etc/hosts file to confirm your hostname is setup correctly
Here is the contents of my hosts file:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 localhost.namenode namenode
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
xxx.xxx.200.143 localhost.namenode namenode
I am not sure what the problem is. Since there are only four steps to run ambari there is not a lot of background to determine the cause of this problem.
