I installed Mapr 5.1 via MapR installer on 4 nodes. Later on, I added 2 nodes via MapR installer. Now I need to add couple more nodes and was planning to do via installer as I did earlier. However, installer is not detecting previous installation and showing options only for a new setup.
a) Is there a way via command line that installer can recognize existing cluster?
b) if a) is not possible and I run installer again - will it detect installations on existing nodes?
Thanks in Advance
