> result of Dataset sort-partition method gives incorrect result when use BigDecimal as key. 
> Here is the test code. The print result does not give the right order.
> {code:java}
> ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
> DataSet<String> ss = env.fromElements("1234567.89", "3456789.12", "2345678.91");
> DataSet<String> result = ss.sortPartition(new KeySelector<String,BigDecimal>() {
>     @Override
>     public BigDecimal getKey(String value) throws Exception {
>         return new BigDecimal(value);
>     }
> }, Order.ASCENDING).setParallelism(1);
> result.print();
> {code}
> It seems that class BigDecComprator some problem and the normalized key cannot be compared correctly.
