Hi Ram,
We only need to pass a delivery unit called HANA_HADOOP_CTLR into HANA. You can refer to this post Hadoop MapReduce as Virtual Functions in HANA
Also there are series of video tutorials in SAP HANA Academy - SDA : Hadoop Enhancements - 1. Creating User [SPS09] - YouTube . Hope this helps.
Best regards,
Ziyi Jiang
