[Elasticsearch user settings and extensions] Increase http.max_initial_line_length

[Xavier_Huberdeau]

Hello,

I'm trying to change the elasticsearch settings yml configuration from elastic.co
When I put http.max_initial_line_length: 32kb, it says:

Your changes cannot be applied

    Elasticsearch - 'http.max_initial_line_length': is not allowed
    Elasticsearch - 'http.max_initial_line_length': is not allowed
    Elasticsearch - 'http.max_initial_line_length': is not allowed

    Elasticsearch - 'http.max_initial_line_length': is not allowed
    Elasticsearch - 'http.max_initial_line_length': is not allowed
    Elasticsearch - 'http.max_initial_line_length': is not allowed

I also tried to change it via terraform but it doesn't work either =>

│ Failed with: {"*****":{"root_cause":[{"type":"illegal_argument_exception","reason":"persistent setting [http.max_initial_line_length], not dynamically updateable"}],"type":"illegal_argument_exception","reason":"persistent setting [http.max_initial_line_length], not dynamically updateable"},"status":400}

Can you tell me how I can increase http.max_initial_line_length?

Thanks

It's not possible to change this, sorry.
