The DC/OS HDFS Service implements a REST API that may be accessed from outside the cluster. The <dcos_url> parameter referenced below indicates the base URL of the DC/OS cluster on which the HDFS Service is deployed.
REST API requests must be authenticated. This authentication is only applicable for interacting with the HDFS REST API directly. You do not need the token to access the HDFS nodes themselves.
If you are using Enterprise DC/OS, follow these instructions to create a service account and an authentication token. You can then configure your service to automatically refresh the authentication token when it expires. To get started more quickly, you can also get the authentication token without a service account, but you will need to manually refresh the token.
If you are using open source DC/OS, follow these instructions to pass your HTTP API token to the DC/OS endpoint.
Once you have the authentication token, you can store it in an environment variable and reference it in your REST API calls:
$ export auth_token=uSeR_t0k3n
The curl examples in this document assume that an auth token has been stored in an environment variable named auth_token.
If you are using Enterprise DC/OS, the security mode of your installation may also require the --ca-cert flag when making REST calls. Refer to Obtaining and passing the DC/OS certificate in cURL requests for information on how to use the --cacert flag. If your security mode is disabled, do not use the --ca-cert flag.
The Plan API provides endpoints for monitoring and controlling service installation and configuration updates.
$ curl -H "Authorization:token=$auth_token" <dcos_url>/service/hdfs/v1/plans/deployThe installation will pause after completing installation of the current node and wait for user input.
$ curl -X POST -H "Authorization:token=$auth_token" <dcos_url>/service/hdfs/v1/plans/deploy/interruptThe REST API request below will resume installation at the next pending node.
$ curl -X PUT <dcos_surl>/service/hdfs/v1/plans/deploy/continue$ curl -H "Authorization:token=$auth_token" dcos_url/service/hdfs/v1/endpoints/hdfs-site.xml$ curl -H "Authorization:token=$auth_token" <dcos_url>/service/hdfs/v1/endpoints/core-site.xmlYou will see a response similar to the following:

The pods API provides endpoints for retrieving information about nodes, restarting them, and replacing them.
A list of available node ids can be retrieved by sending a GET request to /v1/pods:
CLI Example
$ dcos hdfs pods list
HTTP Example
$ curl -H "Authorization:token=$auth_token" <dcos_url>/service/hdfs/v1/pods
[
"data-0",
"data-1",
"data-2",
"journal-0",
"journal-1",
"journal-2",
"name-0",
"name-1",
"zkfc-0",
"zkfc-1"
]
You can retrieve node information by sending a GET request to /v1/pods/<node-id>/info:
$ curl -H "Authorization:token=$auth_token" <dcos_url>/service/hdfs/v1/pods/<node-id>/info
CLI Example
$ dcos hdfs pods info journalnode-0

The replace endpoint can be used to replace a node with an instance running on another agent node.
CLI Example
$ dcos hdfs pods replace <node-id>
HTTP Example
$ curl -X POST -H "Authorization:token=$auth_token" <dcos_url>/service/hdfs/v1/pods/<node-id>/replace
If the operation succeeds, a 200 OK is returned.
The restart endpoint can be used to restart a node in place on the same agent node.
CLI Example
$ dcos hdfs pods restart <node-id>
HTTP Example
$ curl -X POST -H "Authorization:token=$auth_token" <dcos_url>/service/hdfs/v1/pods/<node-id>/restartIf the operation succeeds a 200 OK is returned.
The configuration API provides an endpoint to view current and previous configurations of the cluster.
You can view the current target configuration by sending a GET request to /v1/configurations/target.
CLI Example
$ dcos hdfs config target
HTTP Example
$ curl -H "Authorization:token=$auth_token" <dcos_url>/service/hdfs/v1/configurations/target

You can list all configuration IDs by sending a GET request to /v1/configurations.
CLI Example
$ dcos hdfs config list
HTTP Example
$ curl -H "Authorization:token=$auth_token" <dcos_url>/service/hdfs/v1/configurations
[
"9a8d4308-ab9d-4121-b460-696ec3368ad6"
]
You can view a specific configuration by sending a GET request to /v1/configurations/<config-id>.
CLI Example
$ dcos hdfs config show 9a8d4308-ab9d-4121-b460-696ec3368ad6
HTTP Example
$ curl -H "Authorization:token=$auth_token" <dcos_url>/service/hdfs/v1/configurations/9a8d4308-ab9d-4121-b460-696ec3368ad6
{
... same format as target config above ...
}
Send a GET request to the /v1/state/properties/suppressed endpoint to learn if HDFS is in a suppressed state and not receiving offers. If a service does not need offers, Mesos can "suppress" it so that other services are not starved for resources.
You can use this request to troubleshoot: if you think HDFS should be receiving resource offers, but is not, you can use this API call to see if HDFS is suppressed.
curl -H "Authorization: token=$auth_token" "<dcos_url>/service/hdfs/v1/state/properties/suppressed"
