> 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.
