Hi, I'm finding my custom loader fails to deal with SUM() for fields returned as DataByteArray (as in PigStorage) when its LoadMetadata indicates the field type being float.
I've also changed all the field type to chararray which then doesn't find SUM function for chararray. So is it true that automatic type conversion only kicked in when your loadFunc doesn't implement LoadMetadata? i.e. if your loadFunc implements LoadMetadata, then the schema needs to tell the right type for the fields and the tuple it returns needs to hold the right type?
