-----------------------------------------------------------------
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 ./examples/streaming/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?

> Project: Flink
> Issue Type: Bug
> Components: Client / Job Submission
> Affects Versions: 1.10.0
> Reporter: Rui Li
> Assignee: Kostas Kloudas
> Priority: Blocker
> Fix For: 1.10.0
>
>
> The following program reproduces the issue.
> {code}
> Configuration configuration = GlobalConfiguration.loadConfiguration();
> configuration.set(DeploymentOptions.TARGET, RemoteExecutor.NAME);
> StreamExecutionEnvironment streamEnv = new
> StreamExecutionEnvironment(configuration);
> DataStream dataStream = streamEnv.fromCollection(Arrays.asList(1,2,3));
> dataStream.writeAsText("hdfs://localhost:8020/tmp/output");
> streamEnv.execute();
> {code}
> The job will fail with the follow error, even though the output path doesn't
> exist before job submission:
> {noformat}
> org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.fs.FileAlreadyExistsException):
> /tmp/output already exists as a directory
> {noformat}
