Issuse to get oozi/spark to read from a local cluster and write back to a remote cluster

Hi there,
I am having issues to get oozie spark action to read from hdfs  on one secured cluster and write it back to an hdfs in a remote secured  cluster with kerberos . However ooze/spark can read from the hdfs in a local cluster and write back to hdfs in the same cluster . the oozie job properties file has the following :
sparkOpts=--conf spark.yarn.am.extraJavaOptions=-Diop.version={{iop_full_version}} --conf spark.yarn.access.namenodes=hdfs://namenode1:8020,hdfs://namenode2:8020 

It seems that oozie is not attempting  to get the delegation token for the second namenode which a remote namenode although the abov option is set. Is it any other way to force oozie to request the HDFS delegation token for both name nodes? please help.


Also notice a regular spark can be able to perform the above
