删除索引

1）源代码

@Test

public void deleteIndex(){

// 1 删除索引

client.admin().indices().prepareDelete("blog2").get();

// 2 关闭连接

client.close();

}

2）查看结果

浏览器查看http://hadoop102:9200/blog2

没有blog2索引了。

{"error":{"root_cause":[{"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"blog2","index_uuid":"_na_","index":"blog2"}],"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"blog2","index_uuid":"_na_","index":"blog2"},"status":404}

********自己操作********

Java代码：

@Test public void deleteIndex() { client.admin().indices().prepareDelete("blog").get(); // 关掉连接
 client.close(); }

结果：
