Hi,
Thank you for reporting this.
We have identified this as a bug.
The osdb user param does not work with the new HANA plug-in.
In case you have configured Snap Creator agaent on db host and don't want to use root.
As a workaround for now you can move SC agent out of the DB host on a seperate VM where it can run hdbsql client as root user.
Sorry for the inconvenience, we will add the fix in the next possible release of SC.
Regards,
Kapil
