Cluster ignores configuration changes via API

Elastic Stack Elasticsearch
1

Hi there,

I'm trying to adjust some settings persistently through the API.

For example setting the default number of shards:

CURL Apply change:
curl -XPUT localhost:9200/_cluster/settings -d '{ "persistent" : {
"index.number_of_shards" : 2 } }'

Change Response
{"acknowledged":true,"persistent":{},"transient":{}}

CURL List settings
curl -XGET localhost:9200/_cluster/settings

Settings Response
{"persistent":{},"transient":{}}

Any ideas what's going on? I run version 1.0.0

Best regards,

You can even put an invalid setting such as { "foo" : "bar" } and no error
will be returned. This behavior has always been the norm and I agree with
you that invalid settings should be not ignored but an explicit error
should be thrown.

BTW, here is a list of valid settings:
