-----------------------------------
Summary: Support react to the node decommissioning change state on
yarn and do graceful restart
Key: FLINK-23849
URL: https://issues.apache.org/jira/browse/FLINK-23849
Project: Flink
Issue Type: Improvement
Components: Deployment / YARN
Affects Versions: 1.13.2, 1.13.1, 1.12.2
Reporter: zlzhang0122
Fix For: 1.15.0
Now we are not interested in node updates in
YarnContainerEventHandler.onNodesUpdated, but sometimes we want to evict the
running flink process on the 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 and
then restart it.
