Does Ambari cluster setup request a clean-up for current cluster

jerome_li — Tue, 09 Jan 2018 17:16:39 GMT

Hi,

I have three environment(legacy, testing, prd) which consists of 20 servers.

The cluster has been installed with HDFS, Hive, Sqoop, Oozie, Spark and etc. However, there are different versions installed in each cluster.

It is very difficult for me to do the operation tasks for current clusters so I would like to use Ambari to mange and consolidate all the products and components.

How can I apply the Ambari on current cluster? I do not expect to delete all the Hadoop componets before installing Ambari since there are applications running on current cluster.

Please advice. Thank a bunch in advance.

Adding Ambari for management purpose over an existing cluster is called as "Ambari Takeover".You can find a good discussion over in in the following thread:
