To prevent other questioning about the assignee, I have the changed code ready
locally but I don't have the environment to test. I'd let our customer to test
it internally. Once I get the confirmation, I will submit the PR.

> Allow option similar to mapreduce.job.hdfs-servers.token-renewal.exclude
> ------------------------------------------------------------------------

> Key: SPARK-34295
> URL: https://issues.apache.org/jira/browse/SPARK-34295
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 3.2.0
> Reporter: L. C. Hsieh
> Assignee: L. C. Hsieh
> Priority: Major
>
> MapReduce jobs can instruct YARN to skip renewal of tokens obtained from
> certain hosts by specifying the hosts with configuration
> mapreduce.job.hdfs-servers.token-renewal.exclude=<host1>,<host2>,..,<hostN>.
> But seems Spark lacks of similar option. So the job submission fails if YARN
> fails to renew DelegationToken for any of the remote HDFS cluster. The
> failure in DT renewal can happen due to many reason like Remote HDFS does not
> trust Kerberos identity of YARN etc.
