Resetting the Installer Database

The reset command uninstalls the metadata from the Installer database. reset is for advanced users.

You can reset the Installer database by using the CLI reset command or by using the MapR Installer web interface (Support > Reset Installer).

The reset function can be useful for testing purposes, but use reset with caution. If you reset the installer database while packages are installed on the nodes, you will need to remove the packages manually.

NOTE If you experience a failure while installing or uninstalling, the installer prompts you to retry the operation or uninstall and then reinstall from scratch. You should always retry or uninstall before considering using reset.

This example resets the Installer database. The -nv option specifies that certfificates will not be checked and the output mode is verbose:

./bin/mapr-installer-cli reset -nv
