Hi [~lirui], I tried it on the {{master}} (without my patch) with Yarn and HDFS
and job submission from the command line and I cannot reproduce it. My job is:
{code:java}
StreamExecutionEnvironment streamEnv =
StreamExecutionEnvironment.getExecutionEnvironment();
DataStream dataStream = streamEnv.fromCollection(Arrays.asList(1, 2, 3));
dataStream.writeAsText("hdfs://" + args[0] + ":9000/tmp/output");
streamEnv.execute();
{code}
and the command in the CLI :
{{./bin/flink run ./MY_JOB.jar HOSTNAME}}
Also I tried it with providing parallelism using the {{-p}} option and it still
works.
Could you provide some more details so that I can reproduce it?

Could you attach the running job DAG on JIRA? It sounds weird. If you delete
the file/directory at first and then submit the job with {{parallelism == 1}},
it should work and there should be only one execution instead of 1st execution
and others; in the other case, it should be the case the directory exists if
you set {{parallelism > 1}}.

[~lzljs3620320] but how? I don't see a clear reason since that method
translates the default value placeholder to an effective default value.
