::Go back to Oozie Documentation Index::
The Oozie Web Services API is a HTTP REST JSON API.
All responses are in UTF-8 .
Assuming Oozie is runing at OOZIE_URL , the following web services end points are supported:
Documentation on the API is below; in some cases, looking at the corresponding command in the Command Line Documentation page will provide additional details and examples. Most of the functionality offered by the Oozie CLI is using the WS API. If you export OOZIE_DEBUG then the Oozie CLI will output the WS API details used by any commands you execute. This is useful for debugging purposes to or see how the Oozie CLI works with the WS API.

These endpoints are for submitting, managing and retrieving information of workflow, coordinator, and bundle jobs.
An HTTP POST request with an XML configuration as payload creates a job.
The type of job is determined by the presence of one of the following 3 properties:
Or, if none of those are present, the jobtype parameter determines the type of job to run. It can either be mapreduce or pig.

A created job will be in PREP status. If the query string parameter 'action=start' is provided in the POST URL, the job will be started immediately and its status will be RUNNING .
Coordinator jobs with start time in the future they will not create any action until the start time happens.
A coordinator job will remain in PREP status until it's triggered, in which case it will change to RUNNING status. The 'action=start' parameter is not valid for coordinator jobs.
You can submit a Workflow that contains a single MapReduce action without writing a workflow.xml. Any required Jars or other files must already exist in HDFS.
The following properties are required; any additional parameters needed by the MapReduce job can also be specified here:

A HTTP PUT request starts, suspends, resumes, kills, or dryruns a job.
Request:
PUT /oozie/v1/job/job-3?action=start
Response:
HTTP/1.1 200 OK
Valid values for the 'action' parameter are 'start', 'suspend', 'resume', 'kill', 'dryrun', 'rerun', and 'change'.
Rerunning and changing a job require additional parameters, and are described below:
A workflow job in SUCCEEDED , KILLED or FAILED status can be partially rerun specifying a list of workflow nodes to skip during the rerun. All the nodes in the skip list must have complete its execution.
The rerun job will have the same job ID.
A rerun request is done with a HTTP PUT request with a rerun action.

A coordinator job in RUNNING SUCCEEDED , KILLED or FAILED status can be partially rerun by specifying the coordinator actions to re-execute.
A rerun request is done with an HTTP PUT request with a coord-rerun action .
The type of the rerun can be date or action .
The scope of the rerun depends on the type: * date : a comma-separated list of date ranges. Each date range element is specified with dates separated by :: * action : a comma-separated list of action ranges. Each action range is specified with two action numbers separated by -
The refresh parameter can be true or false to specify if the user wants to refresh an action's input and output events.
The nocleanp paramter can be true or false to specify is the user wants to cleanup output events for the rerun actions.

A coordinator job in RUNNING SUCCEEDED , KILLED or FAILED status can be partially rerun by specifying the coordinators to re-execute.
A rerun request is done with an HTTP PUT request with a bundle-rerun action .
A comma separated list of coordinator job names (not IDs) can be specified in the coord-scope parameter.
The date-scope parameter is a comma-separated list of date ranges. Each date range element is specified with dates separated by :: . If empty or not included, Oozie will figure this out for you
The refresh parameter can be true or false to specify if the user wants to refresh the coordinator's input and output events.
The nocleanp paramter can be true or false to specify is the user wants to cleanup output events for the rerun coordinators.

Response:
HTTP/1.1 200 OK
A coordinator job not in KILLED status can have it's endtime, concurrency, or pausetime changed.
A change request is done with an HTTP PUT request with a change action .
The value parameter can contain any of the following: * endtime: the end time of the coordinator job. * concurrency: the concurrency of the coordinator job. * pausetime: the pause time of the coordinator job.
Multiple arguments can be passed to the value parameter by separating them with a ';' character.
If an already-succeeded job changes its end time, its status will become running.

The optional show-kill parameter shows kill node in the graph. Valid values for this parameter are 1 , yes , and true . This parameter has no effect when workflow fails and the failure node leads to the kill node; in that case kill node is shown always.
The node labels are the node names provided in the workflow XML.
This API returns HTTP 400 when run on a resource other than a workflow, viz. bundle and coordinator.
A HTTP GET request retrieves workflow and coordinator jobs information.

No action information is returned when querying for multiple jobs.
The syntax for the filter is
[NAME=VALUE][;NAME=VALUE]*
Valid filter names are:
The query will do an AND among all the filter names.
The query will do an OR among all the filter values for the same name. Multiple values must be specified as different name value pairs.
Additionally the offset and len parameters can be used for pagination. The start parameter is base 1.
Moreover, the jobtype parameter could be used to determine what type of job is looking for. The valid values of job type are: wf , coordinator or bundle .
A HTTP GET request retrieves a bulk response for all actions, corresponding to a particular bundle, that satisfy user specified criteria. This is useful for monitoring purposes, where user can find out about the status of downstream jobs with a single bulk request. The criteria are used for filtering the actions returned. Valid options (_case insensitive_) for these request criteria are:
Specifying 'bundle' is REQUIRED. All the rest are OPTIONAL but that might result in thousands of results depending on the size of your job. (pagination comes into play then)
If no 'actionStatus' values provided, by default KILLED,FAILED will be used. For e.g if the query string is only "bundle=MyBundle", the response will have all actions (across all coordinators) whose status is KILLED or FAILED
The query will do an AND among all the filter names, and OR among each filter name's values.
The syntax for the request criteria is
[NAME=VALUE][;NAME=VALUE]*
For 'coordinators' and 'actionStatus', if user wants to check for multiple values, they can be passed in a comma-separated manner. *Note*: The query will do an OR among them. Hence no need to repeat the criteria name
All the time values should be specified in ISO8601 (UTC) format i.e. yyyy-MM-dd'T'HH:mm'Z'
Additionally the offset and len parameters can be used as usual for pagination. The start parameter is base 1.
If you specify a coordinator in the list, that does not exist, no error is thrown; simply the response will be empty or pertaining to the other valid coordinators. However, if bundle name provided does not exist, an error is thrown.
Request:
GET /oozie/v1/jobs?bulk=bundle%3Dmy-bundle-app;coordinators%3Dmy-coord-1,my-coord-5;actionStatus%3DKILLED&offset=1&len=50
Note that the filter is URL encoded, its decoded value is user=chitnis . If typing in browser URL, one can type decoded value itself i.e. using '='
Response:
HTTP/1.1 200 OK

The Oozie Web Services API is a HTTP REST JSON API.
All responses are in UTF-8 .
Assuming Oozie is runing at OOZIE_URL , the following web services end points are supported:
Changes in v2 job API:
There is a difference in the JSON format of Job Information API (*/job) particularly for map-reduce action. No change for other actions. In v1, externalId and consoleUrl point to spawned child job ID, and exteranlChildIDs is null in map-reduce action. In v2, externalId and consoleUrl point to launcher job ID, and exteranlChildIDs is spawned child job ID in map-reduce action.
v2 supports retrieving of JMS topic on which job notifications are sent
REST API URL:
GET http://localhost:11000/oozie/v2/job/0000002-130507145349661-oozie-vira-W?show=jmstopic
Changes in v2 admin API:
v2 adds support for retrieving JMS connection information related to JMS notifications.
REST API URL:
GET http://localhost:11000/oozie/v2/admin/jmsinfo
v2/jobs remain the same as v1/jobs
A HTTP GET request retrieves the job information.
Request:
GET /oozie/v2/job/job-3?show=info&timezone=GMT
Response for a workflow job:
HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8
