[ES]ElasticDump

COMMAND ElasticDump INSTALL  

git clone https://github.com/taskrabbit/elasticsearch-dump.git

NodeJS는 기본적으로 설치가 되어 있어야 한다.

COMMAND npm elasticdump

npm install elasticdump -g elasticdump

COMMAND ElasticDump EXE

./elasticdump --input=http://127.0.0.1:9200/idx_shop_autocomplete --out=data.json --type=data

추가적으로 메뉴얼에는 나와 있지 않지만 optimist 모듈이 없다는 Error 메시지가 나오는 경우 
npm를 이용해서 설치를 하면 문제가 없이 해결이 된다.

  --type=mapping
elasticdump \
  --input=http://production.es.com:9200/my_index \
