--------------------------------
Hi [~kkl0u], just confirmed the job succeeds if I write the program as you did.
But the problem persists if I create the stream env as in the description:
{code}
Configuration configuration = GlobalConfiguration.loadConfiguration();
configuration.set(DeploymentOptions.TARGET, RemoteExecutor.NAME);
StreamExecutionEnvironment streamEnv = new
StreamExecutionEnvironment(configuration);
{code}
Debugged and found that in your program, the execution env is created with
default parallelism == 1:
https://github.com/apache/flink/blob/master/flink-clients/src/main/java/org/apache/flink/client/program/ContextEnvironment.java#L51
But my program doesn't go through that code path. Do you think this is an issue
or I shouldn't create the env like that in the first place?

> Affects Versions: 1.10.0

> 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}
