- Name of grid instance.Ignition.state(String)

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.true
if default grid instance was indeed stopped,
false
otherwise (if it was not started).Ignition.stop(boolean)

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.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.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)
@MXBeanDescription(value="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)
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.
