Subject [jira] [Commented] (FLINK-2069) writeAsCSV function in DataStream Scala API creates no file
Date Tue, 26 May 2015 11:31:17 GMT

----------------------------------------

Hello, I rechecked and unfortunately still it is not creating the csv file in my example.

Specifically I am trying the following: 

{code}
    stream.writeAsCsv("/Users/username/Documents/dataSets/UCI-Waveform/waveformResultsCSV").setParallelism(1)
{code} 
and
{code}
    stream.writeAsText("/Users/username/Documents/dataSets/UCI-Waveform/waveformResults.txt").setParallelism(1)
{code}

The txt file is created but the csv is not. The file-path is exactly the same in both cases.
The streaming example that I am running has an iteration which produces the stream to be written
in a file.

After testing it a lot of times, I saw that the file is created in the specified directory
but after a second or two the csv file disappears.

in the specified path.
