Hi, I'm currently using the new version of java api 8.2 with also ES 8.2 in a dockerized instance.

I'm creating indexes through the API and using IndexSettings to add custom setting. One of them is the total fields limit.

So I do:

```auto
      MappingLimitSettings.Builder mappings = new MappingLimitSettings.Builder();
      mappings.totalFields(new MappingLimitSettingsTotalFields.Builder().limit(5000).build());
      return new IndexSettings.Builder()
         .refreshInterval(new Time.Builder().time("-1").build())
         .numberOfReplicas("0")
         .mappings(mappings.build())
         .build();

```

But I get this error:

`[es/indices.create] failed: [illegal_argument_exception] unknown setting [index.mappings.total_fields.limit] did you mean any of [index.mapping.total_fields.limit, index.mapping.nested_fields.limit, index.mapping.dimension_fields.limit]?`

The code is adding the config under mappings but it should be mapping (singular)

am I doing something wrong? or is this in fact a bug?

I'm seeing the same issue, still not fixed in the Java API client 8.2.2:

This

```auto
        IndexSettings settings = new IndexSettings.Builder()
                .mappings(m -> m.totalFields(totalFields -> totalFields.limit(2000)))
                .build();

```

Gets serialized as:

```auto
{"mappings":{"total_fields":{"limit":2000}}}

```

When sending a CreateIndexRequest with such an IndexSettings, request (rightfully) fails, with message:

`[es/indices.create] failed: [illegal_argument_exception] unknown setting [index.mappings.total_fields.limit] did you mean any of [index.mapping.total_fields.limit, index.mapping.nested_fields.limit, index.mapping.dimension_fields.limit]?`

Is there any plan to fix this?

Same issue here.  
I find no way to configure this setting properly using the java api.
