Contributor

Hi, I have upgraded Ambari 2.2 to 2.4 and everything went well as per steps but it failed to start the ambari service and the following is the error

Hi, Good morning, I ran into different issues and I felt it may be easy to do fresh install 2.4 after removing the 2.2. So I went with fresh install.

Thanks

@Ramakrishna Pratapa Thank you for your response. I already have a cluster running with 2.2 and now I upgraded to 2.4. Is it possible to remove ambari completely and install newly for an existing cluster? Can you please point me to the steps.

I don't have any data in the cluster and hence it was easy for me to remove all bits from the nodes and did fresh install with 2.4. But if you have data in the cluster it may be better to proceed with cluster upgrade steps and verify them as you have already upgraded the Ambari to 2.4.

Thanks

Ram
