ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

说明 mysql因为权限问题，只能写数据到 /var/lib/mysql-files/ 路径

select count(1) from xcdqm_store_purchase_total_amount_streaming into outfile ‘/var/lib/mysql-files/xcdqm_store_purchase_total_amount_streaming.count‘

执行成功后，即可在 /var/lib/mysql-files/ 目录下查看到对应的文件

[root@cdh-hadoop-5 ~]# cd /var/lib/mysql-files/
