----------------------------------------
I'm not sure if I understand what this task is about (what are YARN
namespaces?, why are you linking to Apache Spark), but I've assigned you to the
ticket. Maybe the PR code will help me understand.

> When the cluster has multiple nameservices, the client only can obtain the
> token of default nameservice. We should add an configuration in
> YarnConfigOptions to obtain all nameservices refer to
> spark.yarn.access.hadoopFileSystems.
> [yarn-specific-kerberos-configuration|https://spark.apache.org/docs/latest/running-on-yarn.html#yarn-specific-kerberos-configuration].
> I encountered this problem when the directory of yarn logs is in another
> nameservice. It will lead a long waiting for application to run and the log
> can not be aggregated finally.
