Sqoop抽取数据到MySQL时遇到的问题

背景

对数据进行标准的ETL流程的操作
Sqoop ==data==> Hive ETL==sqoop==> MySQL

xxx.properties文件

mysql_driver="jdbc:mysql://localhost:3306/ruozedata_bi"
mysql_username="root"
mysql_password="root"

driver_rep="jdbc:mysql://localhost:3306/bireport?useUnicode=true&characterEncoding=utf8"
username_rep="root"
password_rep="root"

HOSTNAME="localhost" 
PORT="3306"
USERNAME="root"
PASSWORD="root"
DBNAME="bireport" 

tables=ruozedata_operatetrendandcity_rep,ruozedata_dealcompany_rep

第一次报错

The driver has not received any packets from the server.

大概意思是mysql连接超时，解决步骤：

修改driver_rep：
jdbc:mysql://localhost:3306//bireport?useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=false

修改/etc/my.cnf
wait_timeout=31536000
interactive_timeout=31536000

重启mysql

没有效果，再度报错：

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

定位到原因：Caused by: java.net.UnknownHostException: localshot
修改localhost为机器的ip即可
