Planning error when image is of type singularity and source is docker hub


    • Type: Icon: Bug Bug

    • Priority: Icon: Major Major

    • Affects Version/s: 4.9.0, 4.8.4
    • Component/s: Pegasus Planner
    • None

      Pegasus fails to plan a workflow that has a container of type singularity and the image url points to docker hub.

      Example TC:
      cont hic_hq_image

      { type "singularity" image "docker:///papajim/hic_hq:latest" }

      Error Message:

      ERROR while logging metrics The metrics file location is not yet initialized

      Planning the workflow is successful when I I change the container specification in the transformation catalog to type "docker" :
      cont hic_hq_image

      { type "docker" image "docker:///papajim/hic_hq:latest" }

      I have attached a verbose output from the planner. I've tested this with 4.8.4, but the output is from 4.8.2. Still the same error though.
