---------------------------------------------------------------

I have a similar problem when submiting a cluster entity with the remote NN-HA address. 
It would be good to use Oozie prepared configuration when subming a cluster entity too.

The configuration is the below.
    <interfaces>
        <interface type="readonly" endpoint="webhdfs://nameservice1:50070" version="2.5.0"
/>
        <interface type="write" endpoint="hdfs://nameservice1:8020" version="2.5.0" />
