    • Provisioning

      public static final JobState Provisioning
      Once dynamic provisioning is implemented (ie zfs provisioning), wait for dedicated file system to be provisioned. If not dedicated file system is specified, use default working storage. if working storage is more than 80% full, then wait otherwise, use default working storage

    • Downloading

      public static final JobState Downloading
      One or more downloads is in progress. This can be a multi-threaded step. Threads are not managed in the queue.

    • Processing

      public static final JobState Processing
      All downloads complete; perform Merritt Ingest (validate checksum, mint, create system files, notify storage)

    • Recording

      public static final JobState Recording
      Storage is complete; ready for Inventory. The Inventory service will operate on this step.

    • Notify

      public static final JobState Notify
      Invoke callback if needed Notify batch handler that the job is complete

    • Failed

      public static final JobState Failed
      The queue will track the last successful step so that the job can be resumed at the appropriate step.

    • Completed

      public static final JobState Completed
      Storage and inventory are complete, cleanup job folder

    • Deleted

      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
