> Since the `RowTypeInfo#equals()` does not consider the fieldNames , when process data with RowTypeInfo type there may comes an error of the field name.  
> {code:java}
> String [] fields = new String []{"first", "second"};
> TypeInformation<?>[] types = new TypeInformation[]{
> Types.ROW_NAMED(new String[]{"first001"}, Types.INT),
> Types.ROW_NAMED(new String[]{"second002"}, Types.INT) }; StreamExecutionEnvironment execEnv = StreamExecutionEnvironment.getExecutionEnvironment();
> StreamTableEnvironment env = StreamTableEnvironment.getTableEnvironment(execEnv);
> SimpleProcessionTimeSource streamTableSource = new SimpleProcessionTimeSource(fields, types);
> env.registerTableSource("testSource", streamTableSource);
> Table sourceTable = env.scan("testSource");
> System.out.println("Source table schema : ");
> sourceTable.printSchema();
> {code}
> The table shcema will be 
> {code:java}
> Source table schema : 
> root 
> |-- first: Row(first001: Integer) 
> |-- second: Row(first001: Integer) 
> |-- timestamp: TimeIndicatorTypeInfo(proctime)
> {code}
> the second field has the same name with the first field.
> So, we should consider the fieldnames in RowTypeInfo#equals()
