This document describes the Cloudera Manager REST API. All requests and responses are presented in Javascript Object Notation (JSON).
The API resources listed below follow standard Create-Read-Update-Delete (CRUD) semantics where the HTTP request path defines the entity to be acted on and the HTTP method expresses the type of action to perform.
| HTTP Method | Operation |
|---|---|
| POST | Create entries |
| GET | Read entries |
| PUT | Update or edit entries |
| DELETE | Delete entries |
All collections in the API use plural names, 'users', instead of the singular, 'user'. To address a specific user in the system, expand the URL path to include the user identifier. For example, '/users/foo' identifies user 'foo' and '/users/bar' identifies user 'bar'.
| Collection | POST (create) | GET (read) | PUT (update) | DELETE (delete) |
|---|---|---|---|---|
| /users | Create a new user | List all users in the system | Bulk update all users | Delete all users |
| /users/foo | error | Read information about user 'foo' | If user 'foo' exists, update their information; otherwise error. | Delete user 'foo' |
Keep in mind that not all collections support all operations. For example, events in the system are read-only; you cannot create new events with the API.
You can list the entries in a collection using one of two views: 'summary' or 'full'. The default 'summary' view provides the core information about each entry. The 'full' view is more heavyweight and provides a fully expanded view of each entry. The view is controlled by a query parameter called 'view' e.g. 'GET /users?view=full'.
HTTP requests should set the "Content-Type" header to "application/json" for most calls, unless specified otherwise.
The Cloudera Manager API uses HTTP basic access authentication. It accepts the same user credentials as the web interface. Different users may have different levels of access, as defined by their roles. (See the user management API calls for more.) With every authenticated request, the server returns a session cookie, which can be subsequently used for authentication.
The API returns HTTP code in the 400s and 500s upon errors:
See /tools/echoError for a discussion on the body of an error response.
The API can be queried for the latest version it supports. By making a GET request to the '/version' URL, a string will be returned with the highest supported version (for example, "v2").
Note that servers that only support API v1 do not support this call. In that case, a 404 error will be returned, and can be used to detect that the server only supports v1.
The version should be prepended to the path of the REST resources listed below. The documentation of the different resources lists the version which added the particular functionality.
This API supports a Representational State Transfer (REST) model for accessing a set of resources through a fixed set of operations. The following resources are accessible through the RESTful model:

| ParcelResource |

|
This interface describes a parcel resource and all the operations that can be performed on it. All the commands in this resource are modeled as follows: When you execute a command, for example startDownload, that command simply starts the download and returns right away. This is why they are labeled as a synchronous commands. In order to see the progress of the command a call to ParcelResource#readParcel() needs to be made. This will show the current stage and any progress information if the parcel is in a transition stage. Eg. DOWNLOADING, DISTRIBUTING etc. If the command for some reason could not execute properly, an error is returned to the user as part of the synchronous command. A Parcel goes through many stages during its lifecycle. The various stages and their order is described on in ApiParcel |

The requirement and usage of username and password properties are dependent on the clouderaManagerCreatedUser flag. When creating peers, if 'clouderaManagerCreatedUser' is true, the username/password should be the credentials of a user with administrator privileges on the remote Cloudera Manager. These credentials are not stored, they are used to connect to the peer and create a user in that peer. The newly created user is stored and used for communication with that peer. If 'clouderaManagerCreatedUser' is false, which is not applicable to REPLICATION peer type, the username/password to the remote Cloudera Manager are directly stored and used for all communications with that peer. When updating peers, if 'clouderaManagerCreatedUser' is true and username/password are set, a new remote user will be created. If 'clouderaManagerCreatedUser' is false and username/password are set, the stored username/password will be updated. |

Synchronous commands complete immediately, and their results are passed back in the returned command object after the execution of an API call. Outside of that returned object, there is no way to check the result of a synchronous command. Asynchronous commands have unique non-negative IDs. They may still be running when the API call returns. Clients can check the status of such commands using the API. |

transition and reports any errors that may have occurred..
The complete progress of a parcel is broken up into two different reporting indicators - progress and count. Progress is the primary indicator that reports the global state of transitions. For example, when downloading, progress and totalProgress will show the current number of bytes downloaded and the total number of bytes needed to be downloaded respectively. The count and totalCount indicator is used when a state transition affects multiple hosts. The count and totalCount show the current number of hosts completed and the total number of hosts respectively. For example, during distribution, the progress and totalProgress will show how many bytes have been transferred to each host and the count will indicate how many hosts of of totalCount have had parcels unpacked. Along with the two progress indicators, the ApiParcelState shows both errors and warnings that may have turned up during a state transition. |
