Hi,

Any idea why I am getting this error when doing the restart after I have installed Druid service via Ambari on fresh HDP 3.0 cluster? The cluster was deployed using Cloudbreak on Azure. Ambari version 2.7.0.0.

stderr: /var/lib/ambari-agent/data/errors-82.txt

Hi @Paul Norris ,

I just checked what should be the value of 'roleParams' once you are restarting the Appl Timeline server in my local cluster.

[root@anaik1 data]# cat command-961.json |grep -i -5 roleParams
        ]
    },
    "clusterName": "asnaik",
    "commandType": "EXECUTION_COMMAND",
    "taskId": 961,
    "roleParams": {
        "component_category": "MASTER"
    },
    "componentVersionMap": {
        "HDFS": {
            "NAMENODE": "3.0.0.0-1634",

It should be as above. Can you please verify what the value in your's using command

cat /var/lib/ambari-agent/data/command-82.json |grep -i -5 roleParams

If its empty.

I would suggest you restart ambari server once and try again.

If that doesnt worked. See in /var/log/ambari-server/ambari-server.log file while restarting the App timeline server. you will get some exceptions which will give clue whats going wrong.

Hope this helps your in troubleshooting.

Hi @Akhil S Naik ,

I started again with a fresh cluster, upgraded ambari server and agent to the latest version. After the upgrade when I go back into ambari and try and restart ambari metrics service I now get this error: (I've restarted the ambari-server etc.)

With this in the ambari-server.log:

Hi @Paul Norris,

This seems to be new issue, i suggest you resolve this issue by marking the best answer . and start a new thread.

There you post the Exception in code format

i am code format

additionally my initial understanding says this is becuase you have not done post upgrade tasks( which is upgrading AMS) . correct me if i am wrong .

paul_norris · ‎08-10-2018

Hi @Akhil S Naik,

Ok, I will close this and re-open. The code formatting is not working for me, works when I edit not after posting.

I have run the post-upgrade ambari-server task.

Thanks again.

Paul
