PS this is nothing like a Blocker [~merrily01] - please don't mark it as such
> Add regex expression checks for executorEnv in K8S mode
> -------------------------------------------------------
>
> Key: SPARK-29233
> URL: https://issues.apache.org/jira/browse/SPARK-29233
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: 3.0.0
> Reporter: merrily01
> Priority: Minor
> Attachments: error.jpeg, podEnv.jpeg
>
>
> In k8s mode, there are some naming regular expression requirements and checks
> for the key of pod environment variables, such as:
> * In version k8s v-1.10.5, the naming rules for pod env satisfy the
> requirements of regular expressions: [-. _a-zA-Z] [-. _a-zA-Z0-9].*
> * In version k8s v-1.6, the naming rules for pod env satisfy the requirement
> of regular expressions: [A-Za-z_] [A-Za-z0-9_]*
> Therefore, in spark on k8s mode, spark should add relevant regular checking
> rules when creating executor Env, and stricter validation rules should be
> used to filter out illegal key values that do not meet the requirements of
> the naming rules of Env for creating pod by k8s. Otherwise, it will lead to
> the problem that the pod can not be created normally and the tasks will be
> suspended.
>
> To solve the problem above, a regular validation to executorEnv is added and
> committed.
