MySQL创建数据表
CREATE TABLE weblogs(
md5 varchar(32),
url varchar(64),
request_date date,
request_time time,
ip varchar(15))
我的版本是:Server version: 5.5.38-0Ubuntu0.12.04.1-log (Ubuntu)
在使用如下命令导入时会报错:
mysql> LOAD DATA LOCAL INFILE '/home/Hadoop/weblog_entries.txt' INTO table weblogs FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n';
ERROR 1148 (42000): The used command is not allowed with this MySQL version
提示这个版本的mysql不支持这样导入
hadoop@:~$ mysql -uroot<span> --local-infile=1 -p
Enter password:

在连接mysql的时候加上--local-infile的参数 然后导入即可
或者使用如下方式:
mysql -u [youruser] -h [youraddress] -p [yourpassword] [yourdatabase] --local-infile=1 -e "[yourcmd]"
mysql -uroot -p123456 realworld --local-infile=1 -e "LOAD DATA local INFILE '/home/hadoop/weblog_entries.txt' INTO table weblogs FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n'"
原因分析:根据官方的解释是mysql在编译的时候默认把local-infile的参数设为0,就是关闭了从本地load的功能,所以如果需要使用只能自己打开 通过链接的时候把该参数设置为1的方式
另外Windows下面的换行符和linux的是不一样的
Windows换行是\r\n,十六进制数值是:0D0A。
Linux换行是\n,十六进制数值是:0A
