The `writeMode` by setting default is already exist.
It will check whether the file can be overwrite or not in
`FileOutputFormat.java`:
`private static final void initDefaultsFromConfiguration(Configuration
configuration) {
final boolean overwrite =
configuration.getBoolean(ConfigConstants
.FILESYSTEM_DEFAULT_OVERWRITE_KEY,
ConfigConstants.DEFAULT_FILESYSTEM_OVERWRITE);
DEFAULT_WRITE_MODE = overwrite ? WriteMode.OVERWRITE :
WriteMode.NO_OVERWRITE;
final boolean alwaysCreateDirectory =
configuration.getBoolean(ConfigConstants
.FILESYSTEM_OUTPUT_ALWAYS_CREATE_DIRECTORY_KEY,
ConfigConstants.DEFAULT_FILESYSTEM_ALWAYS_CREATE_DIRECTORY);
DEFAULT_OUTPUT_DIRECTORY_MODE = alwaysCreateDirectory ?
OutputDirectoryMode.ALWAYS : OutputDirectoryMode.PARONLY;
}`
> Scala DataStream API does not have writeAsText method which supports WriteMode

> Project: Flink
> Issue Type: Bug
> Components: Scala API, Streaming
> Reporter: Till Rohrmann
>
> The Scala DataStream API, unlike the Java DataStream API, does not support a
> {{writeAsText}} method which takes the {{WriteMode}} as a parameter. In order
> to make the two APIs consistent, it should be added to the Scala DataStream
> API.
