实现看一下具体的使用：

./esm -s http://192.168.0.109:9200 -x "zebra_info_tmp" -w=5 -b=10 -c 10000 --refresh -o=dump.bin

解释： 把192.168.0.109集群内的 zebra_info_tmp 索引下载到本地，然后保存成dum.cin。 -c 指的是每次批量操作的条数。 其他两个具体忘了。请查看官网。

./esm -d http://192.168.0.109:9200 -y "zebra_info_tmp" -c 1000 -b 10 --refresh -i=dump.bin

解释，把本地的内容保存到集群中的zebra_info_tmp 集群中。

二、在我们无法使用工具的情况下，我们该怎么办。

例如原始数据在hive 中的时候，

我们可以利用elasticsearch 的bulk api。

2.1 首先把数据弄成如下的样子，（json格式数据）

"index":"_index":"zebra_info_tmp","_type":"zebra_info","_id":"L1f47bbb97d239" "adcode":"230921","business_circle":"勃利县镇政府","city":"七台河市","citycode":"0464","district":"勃利县","extensions":"avg_price":0,"good_comments":0,"lvl":0,"numbers":0,"other_type":null,"shops":0,"firstly_classification":"金融","formatted_address":"黑龙江省七台河市勃利县新华街道吉祥街5号","location":"45.746754887850216, 130.57131899190972","name":"平安易贷","province":"黑龙江省","secondary_classification":"银行","township":"新华街道","type_name":"金融" "index":"_index":"zebra_info_tmp","_type":"zebra_info","_id":"L15edb0517a1a1" "adcode":"350427","business_circle":"三明汽车北站","city":"三明市","citycode":"0598","district":"沙县","extensions":"avg_price":0,"good_comments":0,"lvl":0,"numbers":0,"other_type":null,"shops":0,"firstly_classification":"金融","formatted_address":"福建省三明市沙县富口镇","location":"26.50277598187647, 117.67915191588664","name":"中国建设银行自助银行","province":"福建省","secondary_classification":"银行","township":"富口镇","type_name":"金融"

2.2 利用bulk api 往elasticsearch 往集群导数据。

具体的bulk api curl $1:9200/_bulk?pretty --data-binary @$JSON_SPILIT_PATH/$file $1 elasticsearch 其中的一个ip， @后面跟着json 数据的文件。
