[大数据]Elasticsearch创建新索引和数据迁移

原来的缩索引创建后就不能修改 只能创建一个新的索引 再把数据从旧索引迁移到新的索引上

创建新索引

PUT gulimall_product
{
    "mappings" : {
      "properties" : {
        "attrs" : {
          "type" : "nested",
          "properties" : {
            "attrId" : {
              "type" : "long"
            },
            "attrName" : {
              "type" : "keyword"

            },
            "attrValue" : {
              "type" : "keyword"
            }
          }
        },
        "brandId" : {
          "type" : "long"
        },
        "brandImg" : {
          "type" : "keyword"

        },
        "brandName" : {
          "type" : "keyword"

        },
        "catalogId" : {
          "type" : "long"
        },
        "catalogName" : {
          "type" : "keyword"

        },
        "hasStock" : {
          "type" : "boolean"
        },
        "hotScore" : {
          "type" : "long"
        },
        "saleCount" : {
          "type" : "long"
        },
        "skuId" : {
          "type" : "long"
        },
        "skuImg" : {
          "type" : "keyword"

        },
        "skuPrice" : {
