      Description of problem:

      While running this pachyderm sample notebook https://github.com/Jooho/pachyderm-operator-manifests/blob/master/notebooks/pachyderm-opencv.ipynb I encountered errors while fetching the output images from S3. The error says the images do not exist.

      According to rhn-support-jlee there is a workaround to solve it (see the section below)

      Prerequisites (if any, like setup, operators/versions):

      Install RHODS

      Install Pachyderm

      Create an instance of Pachyderm

      Steps to Reproduce

      1. Launch JupyterHub from RHODS Dashboard
      2. Spawn a JL using Standard Data Science image
      3. git clone https://github.com/Jooho/pachyderm-operator-manifests/blob/master/notebooks/pachyderm-opencv.ipynb
      4. change the first command in the second cell to replace in the URL "pachyderm" with the namespace where you created the pachyderm instance. 
      5. run all cells (follow the comments)
      6. notice the error in the 7th cell

      Actual results:

      error while fetching the generated images in the sample notebook

      Expected results:

      generated images in the sample notebook can be fetched without errors

      Reproducibility (Always/Intermittent/Only Once):

      Always

      Build Details:

      RHODS v1.5.0

      Pachyderm operator v0.0.8

      Workaround:

      Run the following commands:

      1. oc adm policy add-scc-to-user anyuid -z pachyderm-worker

      2. oc scale rc/pipeline-edges-v1 --replicas=0; oc scale rc/pipeline-edges-v1 --replicas=1
