Caizhi Weng commented on FLINK-15066:
-------------------------------------
>From the perspective of a new user, especially a user from the traditional
>database, insert overwrite is a really strange behavior. It would be nice if
>the appending mode is made as the default behavior.
> Cannot run multiple `insert into csvTable values ()`

> The first insert into success, but the second one failed with exception:

> // Caused by: java.io.IOException: File or directory /.../xxx.csv already
> exists. Existing files and directories are not overwritten in NO_OVERWRITE
