Hi Yuqi, Yes we are running Jupyter Gateway and kernels on k8s and using Spark 2.4's client mode to launch pyspark. In client mode your driver is running on the same pod where your kernel runs.
I am planning to write some blog post on this on some future date. Did you make the headless service that reflects the driver pod name? Thats one of critical pieces we automated in our custom code that makes the client mode works. -Li On Wed, Oct 31, 2018 at 8:13 AM Zhang, Yuqi <yuqi.zh...@teradata.com> wrote: > Hi Li, > > > > Thank you for your reply. > > Do you mean running Jupyter client on k8s cluster to use spark 2.4? > Actually I am also trying to set up JupyterHub on k8s to use spark, that’s > why I would like to know how to run spark client mode on k8s cluster.
