Cloudera Manager Rest API更新服务配置

我想知道是否有人可以帮助我了解如何用RESTAPI更新cloudera manager中运行的服务。

我一直在阅读文档,并试图找到一种方法来更新一些纱线配置,但文档有点不清楚。 https://cloudera.github.io/cm_api/apidocs/v10/path__clusters_-clusterName- services -serviceName-_config.html

我觉得我已经很接近了,但以下是我目前的情况:

curl -X PUT \
     -u <admin_username>:<admin_password> \
     -H "Content-Type: application/json" \
     -d '{"yarn.scheduler.maximum-allocation-mb":4696}' \
     http://<CM_HOST>:7180/api/v10/clusters/spark-2/services/CD-YARN-rrOCWOpV/config

然而,我得到的回应是:

{
  "message" : "Unrecognized property: 'yarn.scheduler.maximum-allocation-mb'"
}

CD-YARN-rrOCWOpV 在服务列表中确定,来自:

http://<CM_HOST>:7180/api/v10/clusters/spark-2/services/

从中我可以看到结果:

{
    "name" : "CD-YARN-rrOCWOpV",
    "type" : "YARN",
    ....
}

非常感谢。

看起来我写错地方了。所需要的是写入角色配置(在本例中是纱线) RESOURCEMANAGER 角色)。

查询角色后,我能够将RESOURCEMANAGER角色的名称标识为 CD-Y76ddf83d-RESOURCEMANAGER-45344d25a0e70b3b594d08b277a10937

然后更新json对象以匹配查询中找到的对象: http://<CM_HOST>/api/v10/clusters/spark-2/services/CD-YARN-rrOCWOpV/roles/CD-Y76ddf83d-RESOURCEMANAGER-45344d25a0e70b3b594d08b277a10937/config?view=full :

curl -X PUT \
     -u <admin_username>:<admin_password> \
     -H "Content-Type: application/json" \
     -d '{"items": [{"name" : "yarn_scheduler_maximum_allocation_mb", "value":"4696"}]}' \
     http://<CM_HOST>/api/v10/clusters/spark-2/services/CD-YARN-rrOCWOpV/roles/CD-Y76ddf83d-RESOURCEMANAGER-45344d25a0e70b3b594d08b277a10937/config

{
  "items" : [ {
    "name" : "resource_manager_java_heapsize",
    "value" : "472907776"
  }, {
    "name" : "yarn_scheduler_maximum_allocation_mb",
    "value" : "4696"
  }, {
    "name" : "yarn_scheduler_maximum_allocation_vcores",
    "value" : "2"
  } ]

再次感谢!!
