Say I have a haddop/spark cluster with 1 master and 5 slave computers.
I am planning to get 3 more new computers, which I want to add to my cluster as 3 more new workers. [ so now I have 1 master and 8 workers]
I would want HDFS installed on all 8 workers. It seems this can be done using the admin UI.
In addition, I also want any hadoop and spark and other packages to be installed on the new workers as well, and configurations updated on the master , so the master knows there are 8 workers now.
How can I use the cloudera manager admin UI to add these new worker computers into my cluster ? The master remains the same.
