    StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();

    final FileSource<String> source =
            FileSource.forRecordStreamFormat(new TextLineInputFormat(), new Path("/tmp/abcxz"))
                    .build();

    env.fromSource(source, WatermarkStrategy.noWatermarks(), "source").print();
    env.execute();
} {code}
