   I've tried this again in all configurations I know (and also pyspark) and it's working for me:
   
   - cluster mode: keytab, local: keytab, no keytab
   - client mode: keytab / no keytab, client in my laptop, client in k8s pod
   - spark-shell and pyspark shell with tgt
   
   I'm building Spark normally. Make sure your images are updated in docker (remember that the pyspark image is *not* built by default anymore).
   
   You should see a log message like this in the executors:
   
   ```
   2018-12-14 18:52:00 INFO  SparkHadoopUtil:58 - Updating delegation tokens for current user.
   ```
