ElasticSearch 复制数据到新的 索引中 copy data to new index
问题：index一旦建立后，无法再修改内部的setting、mapping ，所以只能通过新建备份index，再把data copy过去，然后再把原来的删了，重新建立全新的index
首先需要安装一个插件
elasticsearch-dump
参考官网：https://github.com/taskrabbit/elasticsearch-dump
新建一个修改后的 index
然后通过dump命令同步数据
elasticdump \
--input=http://localhost:9200/cust_2018031916571000000_test\
--output=http://localhost:9200/cust_2018031916571000000 \
--type=dataPUT cust_2018031916571000000
