Example 1 with OriginSettingClient

use of org.opensearch.client.OriginSettingClient in project OpenSearch by opensearch-project.

the class TransportSearchAction method cancelTask.

private void cancelTask(SearchTask task, Exception exc) {
    String errorMsg = exc.getMessage() != null ? exc.getMessage() : "";
    CancelTasksRequest req = new CancelTasksRequest().setTaskId(new TaskId(client.getLocalNodeId(), task.getId())).setReason("Fatal failure during search: " + errorMsg);
    // force the origin to execute the cancellation as a system user
    new OriginSettingClient(client, TASKS_ORIGIN).admin().cluster().cancelTasks(req, ActionListener.wrap(() -> {
    }));
}

Example 2 with OriginSettingClient

use of org.opensearch.client.OriginSettingClient in project OpenSearch by opensearch-project.
