Do all nodes need to do disksetup to format disks during installation? If I want a node just for zookeeper or jobtracker (not need disk), will it need to disksetup? |

Technically you don't need to have raw disks and subsequently run disksetup as long as you don't have mapr-fileserver package (fileserver) role installed on the node. You will not see that node it the list of the nodes on the dashboard though. |
