Instance Method Details

#cancel(arguments = {}) ⇒ Object

Cancels a task, if it can be cancelled through an API. This functionality is Experimental and may be changed or removed completely in a future release. Elastic will take a best effort approach to fix any issues, but experimental features are not subject to the support SLA of official GA features.

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :task_id (String) —

    Cancel the task with specified task id (node_id:task_number)

  • :nodes (List) —

    A comma-separated list of node IDs or names to limit the returned information; use ‘_local` to return information from the node you’re connecting to, leave empty to get information from all nodes

  • :actions (List) —

    A comma-separated list of actions that should be cancelled. Leave empty to cancel all.

  • :parent_task_id (String) —

    Cancel tasks with specified parent task id (node_id:task_number). Set to -1 to cancel all.

  • :wait_for_completion (Boolean) —

    Should the request block until the cancellation of the task and its descendant tasks is completed. Defaults to false

  • :headers (Hash) —

    Custom HTTP headers
