Flink rest api 错误:请求与预期格式 JarRunRequestBody 不匹配

Question

尝试使用以下 rest API 远程运行 flink 作业，但它的抛出错误

curl -X POST -H 'Content-Type: application/json' --data '
{
    "type": "object",
    "id": "urn:jsonschema:org:apache:flink:runtime:webmonitor:handlers:JarRunRequestBody",
    "properties": {
    "programArgsList" : {
      "type" : "array",
      "items" : [
        "input-kafka-server": "****",
        "input-kafka-topics": "****",
        "input-job-name": "****"
      
    }
  }
}
' http://x.x.x.x:8081/jars/810ac968-5d5f-450d-aafc-22655238d617.jar/run

{"errors"：["Request 不匹配预期的格式 JarRunRequestBody."]}

Answer 1

在此处找到的 jar 运行处理程序的请求正文的说明是 jar 运行消息的 JSON 架构规范。您需要在请求中指定的只是properties，而不是"type"和"id"字段。因此，您的请求应如下所示：

curl -X POST -H 'Content-Type: application/json' --data '
{
  "programArgsList" : [
    "--input-kafka-server",
    "value-input-kafka-server",
    "--input-kafka-topics",
    "value-kafka-topics",
    "--input-job-name",
    "value-job-name"
  ],
"parallelism": 30
}

如果有人正在寻找通过 REST API 提交 Flink 作业的 Python 代码。

import json
url = base_url + "/jars/" + jar_id + "/run"
    myheader = {'content-type': 'application/json'}
    mydata = {
        "programArgsList": [
                            "--input-kafka-server", "value-input-kafka-server",
                            "--input-kafka-topics", "value-kafka-topics",
                            "--input-job-name","value-job-name"
                            ],
        "parallelism": 30
    }
    x = requests.post(url, data=json.dumps(mydata), headers=myheader)
