HDFS上创建目录
hdfs dfs -mkdir -p /momo/data
上传到HDFS
hdfs dfs -put /export/data/data1.tsv /momo/data/
hdfs dfs -put /export/data/data2.tsv /momo/data/
加载到Hive表中
load data inpath '/momo/data/data1.tsv' into table db_msg.tb_msg_source;
load data inpath '/momo/data/data2.tsv' into table db_msg.tb_msg_source;
验证结果
select
msg_time,sender_name,sender_ip,sender_phonetype,receiver_name,receiver_network
from tb_msg_source limit 10;
数据来源:聊天业务系统中导出的2021年11月01日一天24小时的用户聊天数据,以TSV文本形式存储在文件中。
