Existing files and directories are not overwritten in NO_OVERWRITE mode. Use OVERWRITE mode to overwrite existing files and directories.

Flink 1.5

This streaming data written to a file

    val stream = env
                 .addSource(new FlinkKafkaConsumer09[String]("md", new
SimpleStringSchema(), properties))
                 .writeAsText("/tmp/md_streaming.txt")
 env.execute("Flink Kafka Example")

The error states

Caused by: java.io.IOException: File or directory /tmp/md_streaming.txt
already exists. Existing files and directories are not overwritten in
NO_OVERWRITE mode. Use OVERWRITE mode to overwrite existing files and
directories.

Is there any append in writeAsText? I tried OVERWRITE but  did not work.

Thanks
