=== Stop rollup job API
|
|
++++
|
|
<titleabbrev>Stop job</titleabbrev>
|

experimental[]
|
|
|
|
This API stops an existing, started rollup job. If the job does not exist an exception will be thrown.
|
|
Stopping an already stopped job has no action.
|
|
|
|
==== Request
|
|
|
|
`POST _rollup/job/<job_id>/_stop`
|
|
|
|
//===== Description
|
|
|
|
==== Path Parameters
|
|
|
|
`job_id` (required)::
|
|
(string) Identifier for the job
|
|
|
|
==== Query Parameters
|
|
|
|
`wait_for_completion` (optional)::
|
|
(boolean) if set to true, causes the API to block until the indexer state completely stops. If set to false, the
|
|
API returns immediately and the indexer will be stopped asynchronously in the background. Defaults to `false`.
|
|
|
|
`timeout` (optional)::
|
|
(TimeValue) if `wait_for_completion=true`, the API will block for (at maximum)
|
|
the specified duration while waiting for the job to stop. If more than `timeout` time has passed, the API
|
|
will throw a timeout exception. Note: even if a timeout exception is thrown, the stop request is still processing and
|
|
will eventually move the job to `STOPPED`. The timeout simply means the API call itself timed out while waiting
|
|
for the status change. Defaults to `30s`
|
|
|
|
==== Request Body
|
|
|
|
There is no request body for the Stop Job API.
|
|
|
|
==== Authorization
|
|
|
|
You must have `manage` or `manage_rollup` cluster privileges to use this API.
|
|
For more information, see
|
|
{xpack-ref}/security-privileges.html[Security Privileges].
|
|
|
|
|
|
==== Examples
|
|
|
|
If we have an already-started rollup job named `sensor`, it can be stopped with:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST _rollup/job/sensor/_stop
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[setup:sensor_started_rollup_job]
|
|
// TEST[s/_stop/_stop?wait_for_completion=true&timeout=10s/]
|
|
|
|
Which will return the response:
|
|
|
|
[source,js]
|
|
----
|
|
{
|
|
"stopped": true
|
|
}
|
|
----
|
|
// TESTRESPONSE
|
|
|
|
If however we try to stop a job which doesn't exist:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST _rollup/job/does_not_exist/_stop
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[catch:missing]
|
|
|
|
A 404 `resource_not_found` exception will be thrown:
|
|
|
|
[source,js]
|
|
----
|
|
{
|
|
"error" : {
|
|
"root_cause" : [
|
|
{
|
|
"type" : "resource_not_found_exception",
|
|
"reason" : "Task for Rollup Job [does_not_exist] not found",
|
|
"stack_trace": ...
|
|
}
|
|
],
|
|
"type" : "resource_not_found_exception",
|
|
"reason" : "Task for Rollup Job [does_not_exist] not found",
|
|
"stack_trace": ...
|
|
},
|
|
"status": 404
|
|
}
|
|
----
|
|
// TESTRESPONSE[s/"stack_trace": .../"stack_trace": $body.$_path/]
|
|
|
|
===== Waiting for the job to stop
|
|
|
|
Since only a stopped job can be deleted, it can be useful to block the StopJob API until the indexer has fully
|
|
stopped. This is accomplished with the `wait_for_completion` query parameter, and optionally a `timeout`:
|
|
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST _rollup/job/sensor/_stop?wait_for_completion=true&timeout=10s
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[setup:sensor_started_rollup_job]
|
|
|
|
The parameter will block the API call from returning until either the job has moved to `STOPPED`, or the specified
|
|
time has elapsed. If the specified time elapses without the job moving to `STOPPED`, a timeout exception will be thrown.
|
|
|
|
If `wait_for_completion=true` is specified without a `timeout`, a default timeout of 30 seconds is used. |
