Generate _SUCCESS (map-reduce style) when folder has been written

[Gwenhael Pasquiers]

Hi,

Sorry if it's already been asked but is there an embedded way for flink to 
generate a _SUCCESS file in the folders it's been writing into (using the write 
method with OutputFormat) ?

We are replacing a spark job that was generating those files (and further 
operations rely on it).

Best regards,
