> Now, the RowResultGenerator and the ScanerResultGenerator will fit the column
> family if the request doesn't contain any column info.
> {code}
> if (rowspec.hasColumns()) {
> //addColumn for get or scan
> } else {
> for (HColumnDescriptor family:
> table.getTableDescriptor().getFamilies()) {
> scan/get.addFamily(family.getName());

> {code}
> The table.getTableDescriptor() will cost 10+ milliseconds in our hbase
> cluster each request. We can remove these code because the server will auto
> add the columns.
