}

原因

field data 的缓存不够用

解决方法

设置fielddata缓存占用jvm内存的40%或更小

curl -XPUT "localhost:9200/_cluster/settings" -H 'Content-Type: application/json' -d '{
  "persistent" : {
    "indices.breaker.fielddata.limit" : "40%" 
  }
}'

返回:

{
    "acknowledged": true,
    "persistent": {
        "indices": {
            "breaker": {
                "fielddata": {
                    "limit": "40%"
                }
            }
        }
    },
    "transient": {}
}
