This note explains how to set the Cloudera Manager rack parameter name on the BDA V4.2 and higher after a rack expansion.
Consider the scenario:
1. A 6 node Starter Rack is expanded to 12 nodes on the same rack.
2. The first 6 nodes are found to have a Cloudera Manager rack parameter of "/<cluster-name>".
3. The new 6 nodes are found to have a Cloudera Manager rack parameter of "/default".
The question is since all 12 nodes are now on the same rack should they all have a Cloudera Manager rack name parameter of"/default", or all "/<cluster-name>", or something else.
