Hello @NumeroUnoNU ,
yes, you either parse the contents of the hdfs-site.xml or you utilise the HDFS Client, so you do not need to worry about implementation details. I've just quickly googled for you an explanation of what is HDFS Client [1]. If you go for the parsing exercise, make sure you are not referencing the NN, otherwise on failover you should prepare your script to handle that situation.
Kind regards:
Ferenc
