If dualroles is installed, the parameter of the presto-install.sh script is dualroles. If worker is installed, the parameter of the presto-install.sh script is worker. Based on the Presto usage habit, you are advised to install dualroles on the active Master nodes and worker on the Core nodes.
• Local VM path: Enter a script path. The script path must start with a slash (/) and end with .sh.
