Hi to all,
I tried to send a file from local storage to ftp server in docker container
(image: stilliard/pure-ftpd) using Flink 1.10 with hadoop 2.8.5. I tried to
do so with the following code:
final ExecutionEnvironment env =
ExecutionEnvironment.getExecutionEnvironment();
DataSource<Tuple1<String>> lines = env.readCsvFile("
file:///path/to/myfile.csv").types(String.class);
lines.writeAsCsv("ftp://user:pass@localhost:21/test";);
env.execute();
After running it I get an exception with the following stacktrace:
Exception in thread "main" java.lang.RuntimeException:

But the directory is created despite the exception. I tried several
ftp-server docker images, but the result is similar. Is it a bug or should
it be done in another way?
Thanks in advance,
Paweł
