When I convert HCatRecord include Date type record to Row, it failed with
the following errors.
* the code
```
PCollection<Row\> p =
pipeline
/*
* Step #1: Read hive table rows from Hive.
*/
.apply(
"Read from Hive source",
HCatToRow.fromSpec(
HCatalogIO.read()
.withConfigProperties(configProperties)
.withDatabase(options.getHiveDatabaseName())
.withTable(options.getHiveTableName())
.withFilter(options.getFilterString())));
```
* error log
```

```
It occurs because HCatalogIO reads Date type as java.sql.Date in HCatRecord,
but Row class doesn't support Date and HCatToRow doesn't care about it.
I think there are two solution about it.
1. Row type supports Date type(java.util.Date or java.sql.Date)
I don't know another IO classes enough, but there may be another IO
classes which has same problem, and this solution may be able to solve those
problem.
2. Add logic to convert Date type to Datetime type in HCatToRow
The impact of change will be smaller then 1. because it doesn't change Row
class.
Which would be better?
