New noteid assigned after restart?

Elastic Stack Elasticsearch
1

Hi,

I noticed a nodeid is always reassigned after the node is shutdown and
started again (restart). Is this by design? This caused master has to
remove the old node and add the new node, whenever the node is crashed and
restarted.

Is there a way to have the node to keep the same id after restart?

thanks
Daniel

Found this -

@Override protected void doStart() throws ElasticsearchException {
add(localNodeMasterListeners); this.clusterState = ClusterState.
builder(clusterState).blocks(initialBlocks).build(); this.updateTasksExecutor
= EsExecutors.newSinglePrioritizing(daemonThreadFactory(settings,
UPDATE_THREAD_NAME)); this.reconnectToNodes = threadPool.schedule(reconnectInterval,
ThreadPool.Names.GENERIC, new ReconnectToNodes()); Map<String, String>
nodeAttributes = discoveryNodeService.buildAttributes(); // note, we rely
on the fact that its a new id each time we start, see FD and "kill -9"
handling final String nodeId = DiscoveryService.generateNodeId(settings);
DiscoveryNode localNode = new DiscoveryNode(settings.get("name"), nodeId,
transportService.boundAddress().publishAddress(), nodeAttributes, version);
DiscoveryNodes.Builder nodeBuilder = DiscoveryNodes.builder().put(localNode)
.localNodeId(localNode.id()); this.clusterState = ClusterState.
builder(clusterState).nodes(nodeBuilder).blocks(initialBlocks).build(); }

The node ID is auto generated, you can set the node.name though.

What is the problem with things being added back in though?
