Hi everyone !
I’m discovering Ambari. I used to install Hadoop cluster with puppet or manually, and i’m trying to evaluate new projects to manage a Hadoop Cluster, so i’m trying Ambari.
I downloaded the latest available version (126.96.36.199), and i configured a brand new cluster to receive the hadoop ambari process, following the instructions of your documentation.
I had to configure a node as a master dedicated to the ambari-server, this node is also a web proxy for the whole cluster (especially for the installation of HDP). Everything is going as planned until the step 8. This is my problem :
I have selected a minimal installation (HDFS, YARN, Nagios, Ganglia, ZooKeeper), and configured my cluster to run with 1 NameNode (master of the services), and 3 datanodes.
On the Review part, every details seems to be fine and my master node can communicate with the other with password-less ssh. But when i click on the “deploy” action button, the installer seems to froze…
I have this message on screen : “Preparing to Deploy: 0 of 23 tasks completed.”
I waited an hour but nothing changed. I tried to redo this step and waited another hour. I checked the log of the ambari-server, it indicates sending and receiving heartbeat from all my hosts, but nothing more. I cheked the log of the ambari-agent(s) , it indicates that no commands were received from the server.
So what is going on with the installer ?
Thank you very much for your time on this topic.
