title: Pachyderm pipeline does not start a job and launches an empty repo
body: <p>I have a JSON configuration for my pipeline in Pachyderm:</p>
  
  <pre><code>{
      "pipeline": {
          "name": "mopng-beneficiary-v2"
      },
      "input": {
          "pfs": {
              "repo": "mopng_beneficiary_v2",
              "glob": "/*"
          }
      },
      "transform": {
          "cmd": ["python3", "/pclean_phlc9h6grzqdhm6sc0zrxjne_UdOgg.py /pfs/mopng_beneficiary_v2/euoEQHIwIQTe1wXtg46fFYok.csv /pfs/mopng_beneficiary_v2//Users/aviralsrivastava/Downloads/5Feb18_master_ujjwala_latlong_dist_dno_so_v7.csv /pfs/mopng_beneficiary_v2//Users/aviralsrivastava/Downloads/ppac_master_v3_mmi_enriched_with_sanity_check.csv /pfs/mopng_beneficiary_v2/Qc.csv"],
          "image": "mopng-beneficiary-v2-image"
      }
  }
  </code></pre>
  
  <p>And my docker file is as follows:</p>
  
  <pre><code>FROM ubuntu:14.04
  
  # Install opencv and matplotlib.
  RUN apt-get update \
      &amp;&amp; apt-get upgrade -y \
      &amp;&amp; apt-get install -y unzip wget build-essential \
          cmake git pkg-config libswscale-dev \
          python3-dev python3-numpy python3-tk \
          libtbb2 libtbb-dev libjpeg-dev \
          libpng-dev libtiff-dev libjasper-dev \
          bpython python3-pip libfreetype6-dev \
      &amp;&amp; apt-get clean \
      &amp;&amp; rm -rf /var/lib/apt
  
  RUN sudo pip3 install matplotlib
  RUN sudo pip3 install pandas
  
  # Add our own code.
  ADD pclean.py /pclean.py
  </code></pre>
  
  <p>However, when I run my command to create the pipeline:</p>
  
  <pre><code>pachctl create-pipeline -f https://raw.githubusercontent.com/avisrivastava254084/learning-pachyderm/master/pipeline.json
  </code></pre>
  
  <p>The files are existing in the pfs:</p>
  
  <pre><code>pachctl put-file mopng_beneficiary_v2 master -f /Users/aviralsrivastava/Downloads/pclean_phlc9h6grzqdhm6sc0zrxjne_UdOgg.py
  ➜  ~ pachctl put-file mopng_beneficiary_v2 master -f /Users/aviralsrivastava/Downloads/5Feb18_master_ujjwala_latlong_dist_dno_so_v7.csv
  ➜  ~ pachctl put-file mopng_beneficiary_v2 master -f /Users/aviralsrivastava/Downloads/ppac_master_v3_mmi_enriched_with_sanity_check.csv
  ➜  ~ pachctl put-file mopng_beneficiary_v2 master -f /Users/aviralsrivastava/Downloads/euoEQHIwIQTe1wXtg46fFYok.csv
  </code></pre>
  
  <p>It should be worth to note that I am getting this from the logs command(<code>pachctl get-logs --pipeline=mopng-beneficiary-v2</code>):</p>
  
  <pre><code>container "user" in pod "pipeline-mopng-beneficiary-v2-v1-lnbjh" is waiting to start: trying and failing to pull image
