      • stop

        @MXBeanDescription("Stops default grid instance. Return true if default grid instance was indeed stopped, false otherwise (if it was not started).")
        boolean stop​(@MXBeanParameter(name="cancel",description="If true then all jobs currently executing on default grid will be cancelled.")
                     boolean cancel)
        Stops default grid instance.
        Parameters:
        cancel - If true then all jobs currently executing on default grid will be cancelled by calling ComputeJob.cancel() method. Note that just like with Thread.interrupt(), it is up to the actual job to exit from execution.
        Returns:
        true if default grid instance was indeed stopped, false otherwise (if it was not started).
        See Also:
        Ignition.stop(boolean)
      • stop

        @MXBeanDescription("Stops Ignite instance by name. Cancels running jobs if cancel is true. Returns true if named Ignite instance was indeed found and stopped, false otherwise.")
        boolean stop​(@MXBeanParameter(name="name",description="Grid instance name to stop.")
                     String name,
                     @MXBeanParameter(name="cancel",description="Whether or not running jobs should be cancelled.")
                     boolean cancel)
        Stops named Ignite instance. If cancel flag is set to true then all jobs currently executing on local node will be interrupted. If Ignite instance name is null, then default no-name Ignite instance will be stopped. It does not wait for the tasks to finish their execution.
        Parameters:
        name - Ignite instance name. If null, then default no-name Ignite instance will be stopped.
        cancel - If true then all jobs currently will be cancelled by calling ComputeJob.cancel() method. Note that just like with Thread.interrupt(), it is up to the actual job to exit from execution. If false, then jobs currently running will not be canceled. In either case, grid node will wait for completion of all jobs running on it before stopping.
        Returns:
        true if named Ignite instance instance was indeed found and stopped, false otherwise (the instance with given name was not found).

        Ignition.stop(String, boolean)
      • stopAll

        @MXBeanDescription("Stops all started grids.")
        void stopAll​(@MXBeanParameter(name="cancel",description="If true then all jobs currently executing on all grids will be cancelled.")
                     boolean cancel)
        Stops all started grids. If cancel flag is set to true then all jobs currently executing on local node will be interrupted. It does not wait for the tasks to finish their execution.

        Note: it is usually safer and more appropriate to stop grid instances individually instead of blanket operation. In most cases, the party that started the grid instance should be responsible for stopping it.

        Parameters:
        cancel - If true then all jobs currently executing on all grids will be cancelled by calling ComputeJob.cancel() method. Note that just like with Thread.interrupt(), it is up to the actual job to exit from execution
