WeatherAnalysis

汇集全国的天气信息并持久化,在需要时进行细化分析.前期的分析需求可依赖于 Elasticsearch 提供.对于 Elasticsearch 缺少的 join 功能,打算用 Spark 填补.

一.环境

• zookeeper : zookeeper-3.4.9
• Kafka : kafka_2.11-0.9.0.1
• Elasticsearch: 2.4.1

二.Maven依赖

3.Elasticsearch 数据表设计

1.索引

每天建一个索引,索引格式为:weather_XXXX_XX_XX

2.类型

只有一个类型:weather_type:

字段名	类型
address_code	Integer
next24hours_detailed	String
today_brief	String
next1day_brief	String
next2day_brief	String
next3day_brief	String
next4day_brief	String
next5day_brief	String
next6day_brief	String

所有的String 类型都分词.

3.记录编号

记录编号采取自增的方式

4.other

5.cankao
