Hi,
This is the rough source codes of the slicer/loadfunc:
public class HadoopStoreStorage extends Utf8StorageConverter
implements LoadFunc, Slicer {
private static final Log LOG = LogFactory.getLog
Hi,
I implemented a custom loadfunc class to read data from a database. This class
implements both Slicer and LoadFunc. It also generates the slices properly. The
problem is that when I perform this query:
A = LOAD 'table_name' USING CustomStorage;
DUMP A;
The PIG gives the
