南大通用GBase 8a 导出时报错FileSystem Error : Permission denied

GBase 8a数据库集群提供select into outfile方式导出数据到文件，由于数据库进程运行在dbaUser，一般都是操作系统gbase用户，所以简单的本地导出的目录，需要gbase用户的写入权限。如果无权限则报FileSystem Error : Permission denied错误。

样例

由于操作系统gbase用户没有权限写入/opt目录，所以报错。

gbase> select * from t1;
+------+-------+
| id   | value |
+------+-------+
|    1 |   234 |
+------+-------+
1 row in set (Elapsed: 00:00:00.00)

gbase> select * from t1 into outfile '/opt/t1.txt' fields terminated by ',';
