I have a HDP cluster (CentOS), that I installed using Ambari (non-sandbox). This cluster has four nodes. When I use the Ambari Dashboard to view the details, I can see various details such as "HDFS Disk usage" etc. However, when I go to the host details page, I see blank boxes, with the title "No Data Available" . This is happening for all the hosts including the master node. The "Ambari Metrics" monitor is also running fine (green). I have not been able to identify the cause of this issue. Can anyone help me fix this issue?issue.png
. I am attaching the screen shot of the dashboard that displays the details of the node.
@Neeraj Sabharwal Please see the answer I posted. I thought the proxy server was the issue, but then I saw that there was an error message for the proxy line, that I took from your URL. So I removed this line and restarted ambari servers and agents on all the nodes. After that I started seeing the details. Sorry I had accepted your answer and then unaccepted it.
If I don't use the proxy settings in ambari-env.sh, the metrics show up correctly, but there are whole bunch of alerts about web UIs not being accessible.
If I use proxy settings in ambari-env.sh, then the metrics don't show up, it shows data unavailable.
I think I had jumped the gun here. I didn't notice that the command '
-Dhttp.proxyPort=<yourProxyPort>' is not being identified by ambari server as valid command. So I deleted this line from the .env file and then restarted ambari server, restarted ambari agent on master server, and restarted ambari agent service on all the other hosts. After this I see that the host page for all the hosts have started showing the graphs!!!. I am not sure what did the trick, but it seems that after I fixed the ntpd issue, I should have tried restarting the ambari-server and ambari-agents.
