一、Fielddata is disabled on text fields by default. Set fielddata=true on [name] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead.

原因：fielddata=true未开启，在ElasticSearch中默认fielddata默认是false的，因为开启Text的fielddata后对内存的占用很高

解决方法

curl -i -H "Content-Type:application/json" -XPUT 127.0.0.1:9200/zipkin:span-2019-05-16/_mapping/span/?pretty  -d'{"span":{"properties":{"name":{"type":"text","fielddata":true}}}}'

二、localhost连接成功，通过IP连接却失败。

修改配置文件elasticsearch.yml

network.host: 0.0.0.0

另外说明，配置子文件地址

mac 6.5版本

/usr/local/etc/elasticsearch/elasticsearch.yml

mac 2.4.1版本

/usr/local/Cellar/elasticsearch-2.4.1/config/elasticsearch.yml
