Orchestrator sunset time is the maximum lifetime for an Orchestrator service. Sunset time determines the maximum amount of time that the Blaze engine can run a mapping job. The default sunset time is 24 hours. After 24 hours, the Orchestrator shuts down, which causes the Blaze Grid Manager to shut down.
You can configure the Orchestrator sunset time to be greater than or less than 24 hours. Configure the following property in the Hadoop connection:
Maximum lifetime for an Orchestrator service, in hours. Default is 24 hours.
You can also disable sunset by setting the property to 0 or a negative value. If you disable sunset, the Orchestrator never shuts down during a mapping run.
