Ron Bodkin commented on HIVE-2639:
----------------------------------
I tried to use a storage handler to allow passing configuration data down, but
the limitations are too severe (e.g., you can't have a partitioned table with a
custom storage handler).
Here's a way I'd like to see Hive's default storage handler implement this:
public class DefaultStorageHandler {
public static final String INPUTFORMAT = "inputformat.";
@Override
public void configureTableJobProperties(TableDesc tableDesc, Map<String,
String> jobProperties) {
for (Map.Entry entry : tableDesc.getProperties().entrySet()) {
String key = entry.getKey().toString();
if (key.startsWith(INPUTFORMAT)) {
jobProperties.put(key.substring(INPUTFORMAT.length()),
entry.getValue().toString());
}
}
}
}

> If you want to use a parameterizable input format in Hive, you currently have
> to either use set to pass a configuration to everything (on each appropriate
> query). It would be nice to have a kind of property in hive that's associated
> with the input format.
> The best option for this today seems to be the storage handler mechanism, but
> that seems a bit heavyweight for this purpose (requiring you to also specify
> an output format and a serde).
