##### fs.output.always-create-directory

false

Boolean

File writers running with a parallelism larger than one create a directory for the output file path and put the different result files (one per parallel writer task) into that directory. If this option is set to "true", writers with a parallelism of 1 will also create a directory and place a single result file into it. If the option is set to "false", the writer will directly create the file directly at the output path, without creating a containing directory.

##### fs.overwrite-files

false

Boolean

Specifies whether file output writers should overwrite existing files by default. Set to "true" to overwrite by default,"false" otherwise.
