Subject REST API occur Invalid HTTP request
Date Fri, 08 Apr 2016 09:53:51 GMT
Hi all,

I got Invalid HTTP request error with message "Detected incorrect link
config structure" when using REST API to create a MySQL link.

My sqoop version is 1.99.6.

I am using "POST /v1/link" API with request body:

{"link":{"id":-1,"enabled":true,"link-config-values":[{"id":1,"inputs":[{"id":1,"name":"linkConfig.jdbcDriver","value":"com.mysql.jdbc.Driver","type":"STRING","size":255,"editable":"ANY","sensitive":false},{"id":2,"name":"linkConfig.connectionString","value":"jdbc:mysql\/\/
tempt61.qserver.com:3306
\/sqoop","type":"STRING","size":255,"editable":"ANY","sensitive":false},{"id":3,"name":"linkConfig.username","value":"sqoop","type":"STRING","size":5,"editable":"ANY","sensitive":false},{"id":4,"name":"linkConfig.password","value":"sqoop","type":"STRING","size":5,"editable":"ANY","sensitive":false},{"id":5,"name":"linkConfig.jdbcProperties","value":{"useUnicode":true},"type":"MAP","editable":"ANY","sensitive":false}],"name":"linkConfig","type":"LINK"}],"update-user":"sqoop","name":"testMysqlLink","creation-date":1460108824566,"connector-id":4,"update-date":1460108824566,"creation-user":"sqoop"}}

I got the response as followed:

Could some one help me figure out where my issue is?

Thanks a lot!
