Enabling auto or manual repair

For each cluster, you can enable auto or manual repair. Manual repair is default.

	Warning
	In order to be able to use the repair feature, you need to set up custom hostnames. This is required because Ambari stores hostname-related metadata in its database and it requires custom hostnames to keep consistent metadata. You can set this up by using either Custom internal hostnames for cluster hosts or Custom hostnames based on DNS on AWS.

Manual repair is used by default for all clusters. If you would like to use auto repair, set “recoveryMode”:”MANUAL” in the CLI JSON. That is, the following repair options are available:

• Manual: “recoveryMode”:”MANUAL” (default)

• Auto: “recoveryMode”:”AUTO”

Additionally, when an HA blueprint is provided, setting auto repair can be done from the web UI. The option is available from the Hardware and Storage page > Enable Auto Recovery. If “Enable Auto Recovery” is not selected, manual recovery is configured by default. This option is not available when using a non-HA blueprint.
