Resets an existing {anomaly-job}.

[[ml-reset-job-request]]
== {api-request-title}

`POST _ml/anomaly_detectors/<job_id>/_reset`

[[ml-reset-job-prereqs]]
== {api-prereq-title}

* Requires the `manage_ml` cluster privilege. This privilege is included in the 
`machine_learning_admin` built-in role.
* Before you can reset a job, you must close it. You can set `force` to `true`
when closing the job to avoid waiting for the job to complete. See 
<<ml-close-job>>.

[[ml-reset-job-desc]]
== {api-description-title}

All model state and results are deleted.
The job is ready to start over as if it had just been created.

It is not currently possible to reset multiple jobs using wildcards or a comma
separated list.

[[ml-reset-job-path-parms]]
== {api-path-parms-title}

`<job_id>`::
(Required, string)
include::{es-repo-dir}/ml/ml-shared.asciidoc[tag=job-id-anomaly-detection]

[[ml-reset-job-query-parms]]
== {api-query-parms-title}

`wait_for_completion`::
  (Optional, Boolean) Specifies whether the request should return immediately or
  wait until the job reset completes. Defaults to `true`.

[[ml-reset-job-example]]
== {api-examples-title}

[source,console]
--------------------------------------------------
POST _ml/anomaly_detectors/total-requests/_reset
--------------------------------------------------
// TEST[skip:setup:server_metrics_job]

When the job is reset, you receive the following results:

[source,console-result]
----
{
  "acknowledged": true
}
----

In the next example we reset the `total-requests` job asynchronously:

[source,console]
--------------------------------------------------
POST _ml/anomaly_detectors/total-requests/_reset?wait_for_completion=false
--------------------------------------------------
// TEST[skip:setup:server_metrics_job]

When `wait_for_completion` is set to `false`, the response contains the id
of the job reset task:

[source,console-result]
----
{
  "task": "oTUltX4IQMOUUVeiohTt8A:39"
}
----
// TESTRESPONSE[s/"task": "oTUltX4IQMOUUVeiohTt8A:39"/"task": $body.task/]

If you want to check the status of the reset task, use the <<tasks>> by referencing 
the task ID.
