当我通过sqoop连接到mysql时，出现以下错误
请帮助我确定这个问题的原因是什么，或者我在命令中遗漏了什么。谢谢！

SERVER DETAILS :
HOSTNAME: SUSDAY1110
PORT: 1433
IP Address: 193.126.45.149

sqoop import --connect jdbc:mysql://193.126.45.149:1433/GMAGH --table ALL_LOB --username root11  --password 'asdad!34' --target-dir /user/sqoop/data/ALL_LOB -m 1

运行命令时出现以下错误：
