    "bucket_id": {
      "terms": {
        "field": "id"
        , "size": 1000
      },
      "aggs": {
        "bucket_name": {
          "terms": {
            "field": "name.keyword"
            , "size": 1
          }

      }
    }

想通了

AggregationBuilder aggregationBuilder = AggregationBuilders.terms("bucket_id").field("id").size(1000);
aggregationBuilder.subAggregation(AggregationBuilders.terms("bucket_name").field("name.keyword"));
