title: CloudML job + verbosity == Error
body: <p>Runnning the <code>dataeng-machine-learning</code> codelab on step <code>9. 4. Feature Engineering</code>.</p>
  
  <p>The notebook step for running a tarin job is:
  <code>
  %%bash
  OUTDIR=gs://${BUCKET}/taxifare/ch4/taxi_trained
  JOBNAME=lab4a_$(date -u +%y%m%d_%H%M%S)
  echo $OUTDIR $REGION $JOBNAME
  gsutil -m rm -rf $OUTDIR
  gcloud ml-engine jobs submit training $JOBNAME \
     --region=$REGION \
     --module-name=trainer.task \
     --package-path=${REPO}/courses/machine_learning/feateng/taxifare/trainer \
     --job-dir=$OUTDIR \
     --staging-bucket=gs://$BUCKET \
     --scale-tier=BASIC \
     --runtime-version=1.0 \
     -- \
     --train_data_paths="gs://$BUCKET/taxifare/ch4/taxi_preproc/train*" \
     --eval_data_paths="gs://${BUCKET}/taxifare/ch4/taxi_preproc/valid*"  \
     --output_dir=$OUTDIR \
     --num_epochs=100
  </code></p>
  
  <p>That works great no matter how many time I run it.</p>
  
  <p>However if I run:
  <code>
  %%bash
  OUTDIR=gs://${BUCKET}/taxifare/ch4/taxi_trained
  JOBNAME=lab4a_$(date -u +%y%m%d_%H%M%S)
  echo $OUTDIR $REGION $JOBNAME
  gsutil -m rm -rf $OUTDIR
  gcloud ml-engine jobs submit training $JOBNAME \
     --region=$REGION \
     --module-name=trainer.task \
     --package-path=${REPO}/courses/machine_learning/feateng/taxifare/trainer \
     --job-dir=$OUTDIR \
     --staging-bucket=gs://$BUCKET \
     --scale-tier=BASIC \
     --runtime-version=1.0 \
     -- \
     --train_data_paths="gs://$BUCKET/taxifare/ch4/taxi_preproc/train*" \
     --eval_data_paths="gs://${BUCKET}/taxifare/ch4/taxi_preproc/valid*"  \
     --output_dir=$OUTDIR \
     --num_epochs=100 \ 
     --verbosity DEBUG
  </code></p>
  
  <p>Job fails after about 40 sec. with this in the logs:
  <code>The replica master 0 exited with a non-zero status of 2. Termination reason: Error.</code></p>
  
  <p>I've found this usage in here:
  <a href="https://cloud.google.com/ml-engine/docs/how-tos/getting-started-training-prediction#cloud-train-single" rel="nofollow noreferrer">https://cloud.google.com/ml-engine/docs/how-tos/getting-started-training-prediction#cloud-train-single</a></p>
  
  <p>So I guesss it's ok to use.</p>
  
  <p>What am I doing wrong?</p>
