zlzhang0122 updated FLINK-23849:
--------------------------------
Description: Now we are not interested in node updates in
YarnContainerEventHandler.onNodesUpdated , but sometimes we want to evict the
running flink process on one node and graceful restart on the other node
because of some unexpected reason such as the physical machine need to be
recycle or the cloud computing cluster need to be migration. Thus, we can react
to the node decommissioning change state, and call the stopWithSavepoint
function and then restart it. (was: Now we are not interested in node updates
