  6. You can perform various actions on a workflow by clicking Workflow and selecting one of the following items from the menu: Import from Shared Files System, Import from Local FS, Reset Workflow, Export, or Preview XML.

    Reset Workflow discards any changes made to the workflow that have not been saved.


    If you import an existing workflow XML file, any comments in the file will be lost.

  7. You can configure various settings that you can apply to workflows by clicking Settings and selecting one of the following items from the menu: Global Configurations, Workflow Credentials, SLA for Workflow, Workflow Parameters, Workflow and Action Versions.

  8. Configure or modify stopping points for workflows by clicking Kill Nodes and selecting Create Kill Node or Manage Kill Nodes.

    Once configured, you select a kill node from the Action Settings for a node.

  10. Reposition the workflow to the center of the workspace by clicking the (Reposition) icon.

  11. Save a nonvalidated draft or a validated version of the workflow by clicking Save.

    You can save the workflow to any location in HDFS for which you have write permissions.

  12. Verify that the XML code in your workflow is correct by clicking Validate.

    Validation only confirms that the XML is properly structured. It does not verify if the workflow will succeed when run.

  13. Pass the valid workflow to the job engine in preparation for running the job by clicking Submit.

    When submitting, you can choose whether or not to start the job. If you do not start the job when you submit it, you can start the job from the dashboard. Submitting a workflow results in the workflow displaying in the dashboard.

  14. View or delete assets you created by clicking Manage Assets.

    Only the user who created an asset can view or delete the asset in Asset Manager.
