Requires the following privileges:
|
|
|
|
* cluster: `manage_ml` (the `machine_learning_admin` built-in role grants this
|
|
privilege)
|
|
* source indices: `read`, `view_index_metadata`
|
|
* destination index: `read`, `create_index`, `manage` and `index`
|

|
== {api-description-title}
|
|
|
|
A {dfanalytics-job} can be started and stopped multiple times throughout its
|
|
lifecycle.
|
|
|
|
If the destination index does not exist, it is created automatically the first
|
|
time you start the {dfanalytics-job}. The `index.number_of_shards` and
|
|
`index.number_of_replicas` settings for the destination index are copied from
|
|
the source index. If there are multiple source indices, the destination index
|
|
copies the highest setting values. The mappings for the destination index are
|
|
also copied from the source indices. If there are any mapping conflicts, the job
|
|
fails to start.
|
|
|
|
If the destination index exists, it is used as is. You can therefore set up the
|
|
destination index in advance with custom settings and mappings.
|
|
|
|
IMPORTANT: When {es} {security-features} are enabled, the {dfanalytics-job}
|
|
remembers which user created it and runs the job using those credentials. If you
|
|
provided <<http-clients-secondary-authorization,secondary authorization headers>>
|
|
when you created the job, those credentials are used.

(Boolean) For a successful response, this value is always `true`. On failure, an

exception is returned instead.
|
|
|
|
`node`::
|
|
(string) The ID of the node that the job was started on.
|
|
If the job is allowed to open lazily and has not yet been assigned to a node, this value is an empty string.

The following example starts the `loganalytics` {dfanalytics-job}:

|
|
|
[source,console]
|
|
--------------------------------------------------
|
|
POST _ml/data_frame/analytics/loganalytics/_start
|
|
--------------------------------------------------
|
|
// TEST[skip:setup:logdata_job]
|
|
|
|
When the {dfanalytics-job} starts, you receive the following results:
|
|
|
|
[source,console-result]
