I tried to make new cluster with ambari, but in confirming host process it stuck at checking for potential problem. please help.
Thanks for the info @Aditya Sirna,
I follow the post and copy the url of step3 and paste to new tab then replace step3 to step4, but after that in assign master process the drop down is empty, there is no hostname option at all.
Looks like there is another thread with similar issue reported Can you please close one of them to avoid duplicity.
This indicates that your Host Registration details might not be persisted properly inside the Ambari Database.
As you are seems to be trying to create a new cluster, So in that case it will be best if you perform ambari-server database reset and then try creating the cluster again that will be quick:
# ambari-server stop # ambari-server reset # ambari-server start
Now try to create the cluster freshly from ambari UI. Also it will be best to use the browser in "Incognito Mode" (Private Mode) to make sure that the browser cache is not causing any issue.
If you still face the same issue then please share the ambari server log with us. Along with One of the Ambari-agent log (and out file).
# ls -l /var/log/amabri-server/ambari-server.log # ls -l /var/log/amabri-agent/ambari-agent.log (ambari-agent.out)
