> {{mapreduce.job.send-token-conf}} is a useful feature in Hadoop (see
> [YARN-5910|https://issues.apache.org/jira/browse/YARN-5910] with which RM is
> not required to statically have config for all the secure HDFS clusters.
> Currently it only works for MRv2 but it'd be nice if Spark can also use this
> feature. I think we only need to pass the config to
> {{LaunchContainerContext}} in {{Client.createContainerLaunchContext}}.
