Ashutosh Chauhan commented on PIG-1686:
---------------------------------------
Currently in load func:
{code}
@SuppressWarnings("unchecked")
public abstract InputFormat getInputFormat() throws IOException;
@SuppressWarnings("unchecked")
public abstract void prepareToRead(RecordReader reader, PigSplit split)
throws IOException;
{code}
should be:
{code}
public abstract InputFormat<? extends WritableComparable<?>, ? extends
Writable> getInputFormat() throws IOException;
public abstract void prepareToRead(RecordReader<? extends
WritableComparable<?>, ? extends Writable> reader, PigSplit split) throws
IOException;
{code}
Similarily in storefunc and storefuncInterface. I think this is
backward-compatible.
> Genericize return types of methods defined in loadfunc / storefunc

> Couple of methods defined in loadfunc and storefuncs should have genericized
> return types. Without that, type safety goes for a toss.
