Install Cloudera Manager in a running CHD cluster

Install Cloudera Manager in a running CHD cluster

Contributor

Hello! I've a cluster up and running.

The cluster is running an old CDH version (5.7.0) with 2 NNs and 43 DNs.

Is it possible to install Cloudera Manager?

Thanks!

 

Guido.

I have been told that in theory you could install CM and get it to manage an existing CDH cluster. I don't the specifics though. It probably includes manually updating the CM db so CM is aware what services are on what host. I imagine it will be painful.

If possible, install CM, set up a new CDH cluster and the migrate. If not, backup any HDFS data and metadata, configs, etc. Anything in an external DB like the Hive metadata should be fine and you can put in the DB configs to reconnect to it.

While it is "possible" , the point of Cloudera Manager is to be that central point for your configurations and manage the cluster. The best option would be to setup another cluster and import your data/config into the Cloudera Manager "managed" cluster.
