ERROR 1 (HY000): Can't create/write to file'/' (Errcode: 13)错误解决

错误现象：

mysql> select 'sz',code,time,openprice,HighPrice,LowPrice,CurPrice,TotalAmount,LastClosePrice 

    -> into outfile '/app/hadoop/data/stocks/sz000001.txt' 
    -> fields terminated by ','
    -> lines terminated by '\n'
    -> from His_Day_1 limit 100;
ERROR 1 (HY000): Can't create/write to file '/app/hadoop/data/stocks/sz000001.txt' (Errcode: 13)


解决办法：
修改目录权限：
[root@nticket1 ~]# chown mysql:mysql /app/hadoop/data/stocks


默认情况下mysql安装后，会自动创建mysql用户和mysql用户组，
数据库会创建在/var/lib/mysql目录下，所要保证数据导出目录有mysql用户权限



再次导出成功
mysql> select 'sz',code,time,openprice,HighPrice,LowPrice,CurPrice,TotalAmount,LastClosePrice 
    -> into outfile '/app/hadoop/data/stocks/sz000001.txt' 
    -> fields terminated by ','
    -> lines terminated by '\n'
    -> from His_Day_1 limit 100;

Query OK, 100 rows affected (0.00 sec)
