Rui Li updated FLINK-15533:
---------------------------
Description:
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}
