我想知道是否有人可以帮助我了解如何使用REST API更新在cloudera Manager中运行的服务。
我一直在浏览文档,并试图找到更新某些纱线配置的方法,但文档有点不清楚。 https://cloudera.github.io/cm_api/apidocs/v10/path__clusters_-clusterName-services-serviceName-_config.html
我觉得我很亲密,但到目前为止我的目标是:
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
但是,我得到了回复说:
{
"message" : "Unrecognized property: 'yarn.scheduler.maximum-allocation-mb'"
}
服务名称CD-YARN-rrOCWOpV
已在以下服务列表中标识:
http://<CM_HOST>:7180/api/v10/clusters/spark-2/services/
我可以从中看到结果:
{
"name" : "CD-YARN-rrOCWOpV",
"type" : "YARN",
....
}
谢谢!
看起来我写错了位置。所需要的是写入角色配置(在这种情况下,它是纱线RESOURCEMANAGER
角色)。
在查询角色后,我能够将RESOURCEMANAGER角色的名称标识为CD-Y76ddf83d-RESOURCEMANAGER-45344d25a0e70b3b594d08b277a10937
然后更新json对象以匹配从查询中找到的对象: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
能够得到成功的回复:
{
"items" : [ {
"name" : "resource_manager_java_heapsize",
"value" : "472907776"
}, {
"name" : "yarn_scheduler_maximum_allocation_mb",
"value" : "4696"
}, {
"name" : "yarn_scheduler_maximum_allocation_vcores",
"value" : "2"
} ]
再次感谢你!!
