                "name" : "JDBC_test_table_Input",
                "type" : "LINK"
            }
        ]

I read the documentation and can't find solution for right structure of json.

Answer 1

I had some json issue as well, i have found this workaround to be quite useful: go to the sqoop2 shell (i type sqoop2 in the prompt of the sqoop2 server machine) when in shell, create the link/job etc' using the shell eg 'create link' command the full doc is here sqoop2 command line shell

now you can fetch the link using the rest api - /v1/link/[lid]
