the issue.
> Spark 2.3.0 on kubernetes
> -------------------------
>
> Key: SPARK-24105
> URL: https://issues.apache.org/jira/browse/SPARK-24105
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: 2.3.0
> Reporter: Lenin
> Priority: Major
>
> Right now its only possible to define node selector configurations
> thruspark.kubernetes.node.selector.[labelKey]. This gets used for both driver
> & executor pods. Without the capability to isolate driver & executor pods,
> the cluster can run into a livelock scenario, where if there are a lot of
> spark submits, can cause the driver pods to fill up the cluster capacity,
> with no room for executor pods to do any work.
>
> To avoid this deadlock, its required to support node selector (in future
> affinity/anti-affinity) configruation by driver & executor.
