我需要你的帮助！
3 天我无法通过 Sqoop Rest API 创建链接。
安装在克劳德拉的 Hadoop 集群上的 Sqoop2 服务器
我发送带有正文的 post 请求：
{
"link" : {
"id" : -1,
"enabled" : true,
"update-date" : 1415287846371,
"creation-date" : 1415287846371,

"creation-user" : "user",

}, {

}, {

},
"type" : "MAP",
"sensitive" : false
}
],
"name" : "JDBC_test_table_Input",
"type" : "LINK"
}
]
}
}
服务器返回错误：

我阅读了文档，但找不到正确的 json 结构的解决方案。
