> The following program reproduces the issue.
> {code}
>     Configuration configuration = GlobalConfiguration.loadConfiguration();
>     configuration.set(DeploymentOptions.TARGET, RemoteExecutor.NAME);
>     StreamExecutionEnvironment streamEnv = new StreamExecutionEnvironment(configuration);

>     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
