Class NodeResourceChangeValidator

  • All Implemented Interfaces:
    ChangeValidator

    public class NodeResourceChangeValidator
    extends Object
    implements ChangeValidator
    Emits restart change actions for clusters where the node resources are changed in a way which requires a "restart" (container recreation) to take effect. Nodes will restart on their own on this condition but we want to emit restart actions to defer applying new config until restart.
