Question

SAP DBTech JDBC: [258]: insufficient privilege: Not authorized
i have selected Tables/Import

Answer 1

Hello,
this is security related problem.
Please see my blog for required privileges (chapter 2.1 Required security authorizations):
SAP HANA - Modeling Content Migration - part 1: Preparations, Security Requirements, Export
I think you are missing IMPORT privilege (but can be other privilege as well).
2.1.3 Target: Import of data content
For table import you need to have IMPORT system privilege and write access to target schema:
    for table creation (and optionally data load): CREATE ANY
    for table dropping and re-creation (and optionally data load): CREATE ANY, DROP
Note: It might look like error but you do not need any other privileges (no need to grant SELECT, INSERT or DELETE privilege).
In case that target schema does not exist and you wish to create is as part of import process you need to grant the user system privileges IMPORT and CREATE SCHEMA (no other privileges are required).
Note: From owner perspective it does not matter who started the import. Object owner is always user SYSTEM.
