It looks like that we just need to implement CarbonFileStorageFomartDescriptor
and CarbonHiveSerde
CarbonInputformat/CarbonOutputformat already exists in master branch
@Liang, can you create a module for hive?
import java.util.Set;
import org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat;
import org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat;
import org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe;
import com.google.common.collect.ImmutableSet;
public class ParquetFileStorageFormatDescriptor extends
AbstractStorageFormatDescriptor {
@Override
public Set<String> getNames() {
return ImmutableSet.of(IOConstants.PARQUETFILE, IOConstants.PARQUET);
}
@Override
public String getInputFormat() {
return MapredParquetInputFormat.class.getName();
}
@Override
public String getOutputFormat() {
return MapredParquetOutputFormat.class.getName();
}
@Override
public String getSerde() {
return ParquetHiveSerDe.class.getName();
}
}

Hi
Agree. Hive has been widely used, this is a consensus?? Apache CarbonData
community already have the plan to support hive integration, look forward to
seeing your contribution on hive integration also :)
