|
|
Cancel a running operation.
|
|
|
|
Cancel is a best-effort method for aborting a running operation. Operations that
|
|
have already completed can not be cancelled. If the operation has passed the
|
|
"point of no-return", cancel will have no effect.
|
|
|
|
An example of "point of no-return" in the context of Upgrade operations would
|
|
be if all the nodes have been upgraded but the operation hasn't been marked as
|
|
complete.
|
|
|
|
Only node pool upgrade operations support cancellation.
