Cloudera Manager API

The Cloudera Manager API provides configuration and service lifecycle management, service health information and metrics, and allows you to configure Cloudera Manager itself. The API is served on the same host and port as the Cloudera Manager Admin Console, and does not require an extra process or extra configuration. The API supports HTTP Basic Authentication, accepting the same users and credentials as the Cloudera Manager Admin Console.

You can also access the Cloudera Manager Swagger API user interface from the Cloudera Manager Admin Console. Go to Support > API Explorer to open Swagger.

Obtaining Configuration Files

  1. Obtain the list of a service's roles:
    http://cm_server_host:7180/api/v41/clusters/clusterName/services/serviceName/roles
  2. Obtain the list of configuration files a process is using:
    http://cm_server_host:7180/api/v41/clusters/clusterName/services/serviceName/roles/roleName/process
  3. Obtain the content of any particular file:
    For example:
    http://cm_server_host:7180/api/v41/clusters/Cluster%201/services/OOZIE-1/roles/
    OOZIE-1-OOZIE_SERVER-e121641328fcb107999f2b5fd856880d/process/configFiles/oozie-site.xml
Similar to finding service properties, you can also find host properties. First, get the host IDs for a cluster with the URL:
http://cm_server_host:7180/api/v41/hosts
This should return host objects of the form:
{
   "hostId" : "2c2e951c-aaf2-4780-a69f-0382181f1821",
   "ipAddress" : "10.30.195.116",
   "hostname" : "cm_server_host",
   "rackId" : "/default",
   "hostUrl" : "http://cm_server_host:7180/cmf/hostRedirect/2c2e951c-adf2-4780-a69f-0382181f1821",
   "maintenanceMode" : false,
   "maintenanceOwners" : [ ],
   "commissionState" : "COMMISSIONED",
   "numCores" : 4,
   "totalPhysMemBytes" : 10371174400
}
Then obtain the host properties by including one of the returned host IDs in the URL:
http://cm_server_host:7180/api/v41/hosts/2c2e951c-adf2-4780-a69f-0382181f1821?view=FULL
