【ELASTICSEARCH】ElasticSearch 爬坑学习

1.了解ES官网的文档，发现在跟着步骤执行时出现了问题

语法：

PUT /megacorp/employee/1
{
    "first_name" : "John",
    "last_name" :  "Smith",
    "age" :        25,
    "about" :      "I love to go rock climbing",
    "interests": [ "sports", "music" ]
}

出现异常：

#! Deprecation: the default number of shards will change from [5] to [1] in 7.0.0; if you wish to continue using the default of [5] shards, you must manage this on the create index request or with an index template

这里描述的大概意思是，ES7.0后已经改变了之前的默认分片 从5变成1，所以你如果想创建上面的索引，需要人工去改分片数量

解决方法，我这边是直接把索引的分片改成1：

PUT /megacorp/_settings
{
    "number_of_replicas": 1
}

再执行上面的新建索引命令创建成功
