This section describes operations you can perform using the Installer.
Using the Enable Secure Cluster Option
You use the Enable Secure Cluster option to control whether or not the cluster is configured as a secure cluster.
Installing NFS Using the Installer
Using the web-based Installer, you can install version 3 or version 4 of the Network File System (NFS) on the cluster.
Using Custom Playbooks
Installer 1.12.0.0 and later enable you to use custom playbooks that can run a set of predefined tasks during or after operations using the Installer or Installer Stanzas.
Using the Incremental Install Function
Use the Incremental Install function of the web-based Installer to control security, add or upgrade services, upgrade Ecosystem Packs (MEPs), and perform other maintenance functions.
Using the MapR Subnet and MapR External Advanced Options
Using the Installer advanced options available under Node Configuration, you can restrict the cluster to a subset of network interface cards (NICs) or specify public IP addresses that can be used with the cluster nodes.
Online vs. Offline Operations
Most Installer operations are offline operations, meaning that the cluster must be brought down in order to perform the operation. But there are some exceptions.
Importing or Exporting the Cluster State
You can use the Import State and Export State commands to upload or download a YAML configuration file (a "Stanza") that describes the state of the cluster.
Performing a Maintenance Update
Perform a maintenance update when you want to upgrade to a new patch version of core or apply a patch.
