I have upgraded Ambari to 184.108.40.206 as described here: https://docs.hortonworks.com/HDPDocuments/Ambari-220.127.116.11/bk_upgrading_Ambari/bk_upgrading_Ambari-201...
Ambari works and all, the only problem that I have is in the ambari-server.log. I am getting these ERROR messages constantly:
What is interesting here is that in this cluster, I dont have hive, pig, ranger and tez installed. Any ideas how to fix this?
EDIT: I see now that I am getting metrics correctly from the datanode, while the name node is giving me No Data Available.
Did what you advised me, @Rahul Pathak. after doing the post-upgrade I managed to get Grafana started and some metrics are showing, but not the ones from namenode.
I see I get the same error messages. Its funny, the error messages are mentioning services I dont have installed - hive, tez, pig, ranger...
Check ambari database in tables
for service name you are seeing in the logs.
