【大数据基础】基于信用卡逾期数据的Spark数据处理与分析
https://dblab.xmu.edu.cn/blog/2707/
实验过程
数据预处理
本次实验数据集来自和鲸社区的信用卡评分模型构建数据，以数据集cs-training.csv为分析主体，其中共有15万条记录，11列属性。
每个数据包含以下字段：
字段名称 字段含义 例子
（1）SeriousDlqin2yrs 是否逾期 0,1
（2）RevolvingUtilizationOfUnsecuredLines 信用卡和个人信贷额度的总余额 0.766126609
（3）Age 年龄 45,20,30
（4）NumberOfTime30-59DaysPastDueNotWorse 借款人逾期30-59天的次数 0,2,3
（5）DebtRatio 负债比率 0.802982129
（6）MonthlyIncome 月收入 9120,3000
（7）NumberOfOpenCreditLinesAndLoans 未偿还贷款数量 ,0,4,13
（8）NumberOfTimes90DaysLate 借款人逾期90天以上的次数 0,1,3
（9）NumberRealEstateLoansOrLines 房地产贷款的数量 3,6
（10）NumberOfTime60-89DaysPastDueNotWorse 借款人逾期60-89天的次数 0,3
（11）NumberOfDependents 家庭中的家属人数 0,1,3
本次实验采用pandas库对数据进行预处理。在实验中，不对信用卡和个人信贷额度的总余额、负债比率、未偿还贷款数量、逾期90天以上的次数这4个属性进行处理分析。
具体处理步骤如下：
（1）读取数据
（2）查看数据是否具有重复值，去除重复值
（3）查看各字段缺失率，缺失值以均值填充
（4）选取要研究的属性，删除不研究的属性
（5）保存文件到本地
使用代码文件data_preprocessing.py对数据预处理，运行data_preprocessing.py文件的步骤如下：
import pandas as pd# 读取数据
df = pd.read_csv("~/Desktop/cs-training.csv")# 去除重复值
df.duplicated()
df.drop_duplicates()# 查看各字段缺失率
df.info()
# 缺失值按均值填充
for col in list(df.columns[df.isnull().sum() > 0]):mean_val = df[col].mean()df[col].fillna(mean_val, inplace=True)# 删除不分析的列
columns = ["RevolvingUtilizationOfUnsecuredLines","DebtRatio","NumberOfOpenCreditLinesAndLoans","NumberOfTimes90DaysLate"]
df.drop(columns,axis=1,inplace=True)# 保存到本地
df.to_csv("~/OverDue/data.csv")
将文件上传至HDFS文件系统
# 启动Hadoop
cd /usr/local/hadoop
./sbin/start-dfs.sh
# 在HDFS文件系统中创建/OverDue目录
./bin/hdfs dfs -mkdir /data
# 上传文件到HDFS文件系统中
./bin/hdfs dfs -put ~/OverDue/data.csv /OverDue/data.csv
使用Spark对数据处理分析
我们将采用Python编程语言和Spark大数据框架对数据集“data.csv”进行处理分析，具体步骤如下：
（1）读取HDFS文件系统中的数据文件，生成DataFrame
（2）修改列名
（3）本次信用卡逾期的总体统计
（4）年龄与本次信用卡逾期的结合统计
（5）两次逾期记录与本次信用卡逾期的结合统计
（6）房产抵押数量与本次信用卡逾期的结合统计
（7）家属人数与本次信用卡逾期的结合统计
（8）月收入与本次信用卡逾期的结合统计
（9）将统计数据返回给数据可视化文件data_web.py
./bin/hdfs dfs -put ~/OverDue/data1.csv /user/hadoop
