Close Job API
editClose Job API
editThe Close Job API provides the ability to close machine learning jobs in the cluster.
It accepts a CloseJobRequest
object and responds
with a CloseJobResponse
object.
Close Job Request
editA CloseJobRequest
object gets created with an existing non-null jobId
.
CloseJobRequest closeJobRequest = new CloseJobRequest("closing-my-first-machine-learning-job", "otherjobs*"); closeJobRequest.setForce(false); closeJobRequest.setAllowNoJobs(true); closeJobRequest.setTimeout(TimeValue.timeValueMinutes(10));

Optionally used to close a failed job, or to forcefully close a job which has not responded to its initial close request. |

Optionally set to ignore if a wildcard expression matches no jobs.

Close Job Response
editSynchronous Execution
editWhen executing a CloseJobRequest
in the following manner, the client waits
for the CloseJobResponse
to be returned before continuing with code execution:
CloseJobResponse closeJobResponse = client.machineLearning().closeJob(closeJobRequest, RequestOptions.DEFAULT);
Synchronous calls may throw an IOException
in case of either failing to
parse the REST response in the high-level REST client, the request times out
or similar cases where there is no response coming back from the server.
In cases where the server returns a 4xx
or 5xx
error code, the high-level
client tries to parse the response body error details instead and then throws
a generic ElasticsearchException
and adds the original ResponseException
as a
suppressed exception to it.
Asynchronous Execution
editExecuting a CloseJobRequest
can also be done in an asynchronous fashion so that
the client can return directly. Users need to specify how the response or
potential failures will be handled by passing the request and a listener to the
asynchronous close-job method:
The asynchronous method does not block and returns immediately. Once it is
completed the ActionListener
is called back using the onResponse
method
if the execution successfully completed or using the onFailure
method if
it failed. Failure scenarios and expected exceptions are the same as in the
synchronous execution case.
A typical listener for close-job
looks like:
