Updating node settings

Elastic Stack Elasticsearch
1

Hello,
I would like to update the settings of all the nodes in our cluster without
having to restart them. The settings are the following:
PUT _cluster/settings
{
"persistent" : {
"gateway.type": "local",
"gateway.recover_after_nodes": 3,
"gateway.expected_nodes": 3,
"gateway.recover_after_time": "30m",
"gateway.local.auto_import_dangled": "no",
"gateway.local.dangling_timeout": "30m"
}
}

After executing the precious instruction I get an "aknowledge:true" answer,
however when I try to get the settings via "get _nodes/settings", those
settings are not updated at all. Any idea why this happens? Do these
settings require a restart?

Kind regards,

Ernesto

Maybe because you are looking at _node when you applied it to _cluster, see
if they are returned when you get _cluster/settings.

Cluster settings are applied to the nodes, but they are not "stored' in the
same API endpoint.

That was the first place I look into (get _cluster/settings), and I just
got:
{
"persistent": {},
"transient": {}
}

Then that's not a setting you can apply via the API, you need to edit the
elaticsearch.yml and restart unfortunately.
