  title: Databricks Clone a Job From an Existing One
  summary: Read an existing job's settings and create a new job that reuses them.
  description: >-
    Fetches the settings of an existing Databricks job and uses those task and
    cluster definitions to create a brand new job under a different name,
    effectively cloning a job template. The settings object read from the source
    job feeds the create request's task and job cluster lists. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
