h1. What about driver HostNetwork on k8s mode？Does it also need the same
processing?

> Project: Spark
> Issue Type: New Feature

> Affects Versions: 4.0.0
> Reporter: zzzzming95
> Priority: Major
> Labels: pull-request-available
>
> In k8s mode, when the executor executes the host network mode, it means that
> the executor shares the same IP address with the host. To support this mode
> in Spark, spark need to allow the Executor to be launched using a random
> BlockManager port. And prohibit shuffle local read, as this will cause the
> shuffle to be read failed.
