有哪些网站是封面型/站长工具端口查询

一、zeppelin的安装

zeppelin解压后进入到conf配置文件界面。

1. 修改zeppelin-site.xml

[root@hadoop02 conf]# cp zeppelin-site.xml.template zeppelin-site.xml
[root@hadoop02 conf]# vim zeppelin-site.xml

将IP地址和端口号设置成自己的

2. 修改 zeppelin-env.sh

export JAVA HOME=/opt/soft/jdk180
export HADOOP HOME=/opt/soft/hadoop313
export HADOOP CONF DIR=/opt/soft/hadoop313/etc/hadoop

3. 将hive-site.xml拷贝到zeppelin中

[root@hadoop02 conf]# cp /opt/soft/hive312/conf/hive-site.xml /opt/soft/zeppelin/conf

4. 添加jar包

路径切换到/opt/soft/zeppelin/interpreter/jdbc下，添加如下jar包：

[root@hadoop02 jdbc]# cp /opt/soft/hadoop313/share/hadoop/common/hadoop/common-3.1.3.jar ./
[root@hadoop02 jdbc]# cp /opt/soft/hive312/lib/curator-client-2.12.0.jar ./
[root@hadoop02 jdbc]# cp /opt/soft/hive312/lib/guava-27.0-jre.jar ./
[root@hadoop02 jdbc]# cp /opt/soft/hive312/lib/hive-jdbc-3.1.2.jar ./
[root@hadoop02 jdbc]# cp /opt/soft/hive312/lib/hive-serde-3.1.2.jar ./
[root@hadoop02 jdbc]# cp /opt/soft/hive312/lib/hive-service-3.1.2.jar ./
[root@hadoop02 jdbc]# cp /opt/soft/hive312/lib/hive-service-rpc-3.1.2.jar ./
[root@hadoop02 jdbc]# cp /opt/soft/hive312/lib/libthrift-0.9.3.jar ./
[root@hadoop02 jdbc]# cp /opt/soft/hive312/lib/protobuf-java-2.5.0jar ./

添加外部jar包：

5. 配置profile文件

# ZEPPELIN_HOME
export ZEPPELIN_HOME=/opt/soft/zeppelin
export PATH=$PATH:$ZEPPELIN_HOME/bin

6. 启动zeppelin

[root@hadoop02 jdbc]# zeppelin-daemon.sh start

打开浏览器

二、数据结构

1. 数据准备

表数据存放在本地的/opt/stufile/storetransaction中。

1. 检查行数
[root@hadoop02 storetransaction]# wc -l customer_details.csv
501 customer_details.csv2. 查看文件header行
[root@hadoop02 storetransaction]# head -n 2 customer_details.csv 
customer_id,first_name,last_name,email,gender,address,country,language,job,credit_type,credit_no
1,Spencer,Raffeorty,[e-mail],Male,9274 Lyons Court,China,Khmer,Safety Technician III,jcb,3589373385487669

2. 创建对应目录

1. 创建数据库
drop database if exists shopping cascade;
create database if not exists shopping;2. hdfs中创建目录，用于保存数据表
hdfs dfs -mkdir -p /shopping/data/customer
hdfs dfs -mkdir -p /shopping/data/store
hdfs dfs -mkdir -p /shopping/data/review
hdfs dfs -mkdir -p /shopping/data/transcation3. 将本地数据上传到hdfs
hdfs dfs -put ./customer_details.csv /shopping/data/customer
hdfs dfs -put ./store_details.csv /shopping/data/store
hdfs dfs -put ./store_review.csv /shopping/data/review
hdfs dfs -put ./transaction_details.csv /shopping/data/transcation4. 查看hdfs目录中保存的文件
hdfs dfs -ls /shopping/data/customer
hdfs dfs -ls /shopping/data/review
hdfs dfs -ls /shopping/data/store
hdfs dfs -ls /shopping/data/transcation

3. 建表语句

创建外部表，表相关信息存储在hdfs中。

1. 顾客详细表
create external table if not exists ext_customer_details(customer_id string,first_name  string,last_name   string,email       string,gender      string,address     string,country     string,language    string,job         string,credit_type string,credit_no   string
)
row format serde 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
location '/shopping/data/customer'
tblproperties('skip.header.line.count'='1');2. 交易信息表
create external table if not exists ext_transaction_details(transaction_id  string,customer_id     string,store_id        string,price           decimal(8,2),product         string,purchase_date            string,purchase_time            string
)
row format serde 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
location '/shopping/data/transcation'
tblproperties('skip.header.line.count'='1');3. 店铺信息表
create external table if not exists ext_store_details(store_id        string,store_name      string,employee_number string
)
row format serde 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
location '/shopping/data/store'
tblproperties('skip.header.line.count'='1');4. 评分表
create external table if not exists ext_review_details(transaction_id  string,store_id        string,review_score    string
)
row format serde 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
location '/shopping/data/review'
tblproperties('skip.header.line.count'='1');

三、数据清洗

数据脱敏

在customer表中，email字段、address字段、credit_no字段不希望被显示为明文，需要对其进行加密。

drop view if exists vw_customer_details;
create view if not exists vw_customer_details as
select 
customer_id,first_name,unbase64(last_name) as last_name,
unbase64(email) as email, gender,unbase64(address) as address,
country,job,credit_type,
unbase64(concat(unbase64(credit_no),'hello')) as credit_no
from  ext_customer_details;

去除重复值

with
basetb as (select  row_number()over(partition by transaction_id) as rn,transaction_id,customer_id,store_id,price,product,purchase_date,purchase_time,substr(purchase_date,0,7) purchase_month from ext_transaction_details),
basetb2 as (select if(rn=1,transaction_id,concat(transaction_id,'_fix',rn)) transaction_id ,customer_id,store_id,price,product,purchase_date,purchase_time,purchase_month from basetb)
select * from basetb2 where transaction_id like '%fix%' limit 100;

过滤掉缺失内容

create view if not exists vm_store_review as
select * from ext_store_review where review_score <> '';

四、数据分析

Customer分析

• 1.1 找出顾客最常用的信用卡

select credit_type, count(customer_id)
from ext_customer_details group by credit_type;

• 1.2 找出客户资料中排名前五的职位名称

selectcredit_type,count(credit_type) count_credit_type
from  vw_customer_details group by credit_type order by credit_type having gender='female';

• 1.3 在美国女性最常用的信用卡

selectcredit_type,count(credit_type) count_credit_type
from  vw_customer_details 
where gender='Female' and country='United States' 
group by credit_type

from transaction_details)
select concat_quarter1,sum(price) from t2 group by concat_quarter1;或者直接使用季度函数
with t2 as (select concat_ws('-',cast(year(purchase_date) as string),cast(ceil(month(purchase_date)/3) as string)) as concat_quarter1,price
from transaction_details)
select concat_quarter1,sum(price) from t2 group by concat_quarter1;

group by dayofweek(purchase_date);

• 按照工作日、月、季度、年计算总收入

with basetb as(
SELECTprice,dayofweek(purchase_date) as weekday,month(purchase_date) as month,concat_ws('-',cast(year(purchase_date) as string),cast(ceil(month(purchase_date)/3) as string)) as quarter,year(purchase_date) as year
from transaction_details)
select sum(price) as sumMoney,weekday,month,quarter,year from basetb group by weekday,month,quarter,year

• 2.5 按时间段计算总收入(需要清理数据)

这里的时间格式不统一，有24时记时，也有12时记时，需要对数据进行整合。

解体思路：

按时间段计算总收入

early morning(5:00-8:00)

morning(8:00-11:00)

noon(11:00-13:00)

afternoon(13:00-18:00)

evening(18:00-22:00)

night(22:00-5:00)

1. 将12时转换为24时
selectif(purchase_time like '%M',from_unixtime(unix_timestamp(purchase_time,'hh:mm aa'),'HH:mm'),purchase_time) as time_form
from transaction_details;2.分段进行分析
with
basetb as (
selectprice,purchase_time,if(purchase_time like '%M',from_unixtime(unix_timestamp(purchase_time,'hh:mm aa'),'HH:mm'),purchase_time) as time_format
from transaction_details),
basetb2 as (
select price,purchase_time,time_format,cast(split(time_format,':')[0] as decimal(4,2)) +cast(split(time_format,':')[1] as decimal(4,2))/60 as `purchase_time_num`
from basetb
)
select price,purchase_time,if(purchase_time_num>5 and purchase_time_num<=8,'early morning',if(purchase_time_num>8 and purchase_time_num<=11,'morning',if(purchase_time_num>11 and purchase_time_num<=13,'noon',if(purchase_time_num>13 and purchase_time_num<=18,'afternoon',if(purchase_time_num>18 and purchase_time_num<=22,'evening','night'))))) as time_bucket
