ElasticSearch的备份迁移方案

使用插件repository-hdfs插件进行测试

1、需要分发到各个节点，然后进行安装

bin/plugin install file:///home/dinpay/elasticsearch-repository-hdfs-2.3.4.BUILD-20160731.045929-24-hadoop2.zip 

2、将hadoop的etc/hadoop 的hdfs-site.xml和core-site.xml复制到es的每个节点的config目录下（高可用需要的操作）

3、在elasticsearch.yml配置文件后加上

# 禁用jsm,使快照能保存于hdfs

security.manager.enabled: false

repositories.hdfs:

uri: "hdfs://bi"

path: "/es"

load_defaults: "true"

concurrent_streams: 5

conf_location: "core-site.xml,hdfs-site.xml"

compress: "true"

conf.dfs.client.read.shortcircuit: "true"

4、使用kopf插件

#kopf插件 
bin/plugin install lmenezes/elasticsearch-kopf 

#head插件

bin/plugin install mobz/elasticsearch-head 

通过hadoop的文件操作实现迁移文件操作
