How to view Elasticserarch AWS cluster settings
amazon-web-services, elasticsearch, settings
Solution
Yes, it is an AWS constraint on ElasticSearch prior to version 5.3.
Prior to Elasticsearch 5.3, the _cluster/settings API on Amazon ES domains supported only the HTTP PUT method, not the GET method.
AWS supports `_cluster/settings` after Elasticsearch 5.3, and other Elasticsearch operations, but not all. You can refer to their doc: https://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/aes-supported-es-operations.html#es_version_api_notes
Problem
I'm trying to update elasticsearch cluster settings on AWS, but i got this error: ``` Message: "Your request: '/_cluster/settings' is not allowed for verb: GET" ``` My command: ``` curl -XGET localhost:9200/_cluster/settings ``` Obs: both Get or Put method not work ``` curl -XPUT http://localhost:9200/_cluster/settings -d '{"persistent" : {"indices.fielddata.cache.size" : "30%"}}' {"Message":"Your request: '/_cluster/settings' payload is not allowed."} ``` Reference: https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-update-settings.html It's a AWS issue?
