Use bigint for Long values

[tlbollwitt]

The generated table definition uses 'int' data types for values that are longs. The 'curated' JSON document used Long.MAX_VALUE as the field value.

The scalarNumericType() method should probably attempt convert the value to an int and if that fails then return bigint instead of int.

I add some codes and have no problem. Please refer this.

private String scalarNumericType(Object o) {
    String s = o.toString();
    System.out.println(s.getClass().getName());
    if (s.indexOf('.') > 0) {
      return "double";
    }
    else if(Long.parseLong(s) > Integer.MAX_VALUE){
      return "bigint";
    }
    else {
      return "int";
    }
  }
