使用插件repository-hdfs插件进行测试

下载地址：

https://oss.sonatype.org/content/repositories/snapshots/org/elasticsearch/elasticsearch-repository-hdfs/2.3.4.BUILD-SNAPSHOT/elasticsearch-repository-hdfs-2.3.4.BUILD-20160731.045929-24-hadoop2.zip

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hdfssecurity.manager.enabled: falserepositories.hdfs:uri: "hdfs://bi"path: "/es"load_defaults: "true"concurrent_streams: 5conf_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
