Activity monitor Issue

[#1]

Hi

I have a 4 node cluster and the node on which Activity monitor service of Cloudera manager service is running is gone down.

In cloudera manager service, i am not getting option to change this role to another host. It is frustrating. In the configuration page i have changed the property also to different host. still it is not getting out. I need to decomission this host and add another node.

How to resolve this issue ? i want to change the role instance of Actvity monitor to another role. The wizard is also not showing any option

Can you stop the service and delete through CM . Next go to add service and you can see Host monitor option to add to new node.

Hi

I have tried that. The service is not getting stopped. Even the inspect hosts on that node results into error. So when i want to decommission node, it says Cloudera Manager Activity Monitor is running stop it first. When i try to stop activity monitor on that node it times out after 90 seconds.

The screenshot is given below:

The highlighted service 'host' is not available in the cluster. The service is is still started condition and it is not getting stopped.

I am not able to move Activity Monitor to another role instance either, there is no option. Can you assist me in resolving this.

Do i need to create the am and nav databases on different host. At present i want to stop service and delete this host. add this service to new role instance

Hi,

I have to delete that node from azure. then Cloudera was not able to find it and i was able to stop and delete the service. Earlier i only stopped that node in Azure. Somehow it still was able to attached to it. Anyhow, that node was of no use so i deleted it. I was able to move the Activity monitor to different host by creating the database for it.

Also, the de-commissioning and deletion of host is also done from cluster. The parcel distribution is also fine now.
