Adam Szita commented on PIG-5110:
---------------------------------
[~knoguchi], the latter. So for instance, given relation A and B, both with lot
of fields a0,a1,a2... and b0,b1,b2... respectively, right now we would get a
schema like this after JOIN:
A::a0, A::a1, A::a2 ... B::b0, B::b1, ...
Instead of this, we could add a feature to turn off the A:: and B:: prepending
of field aliases, and expect a result having a schema like:
a0,a1,a2... and b0,b1,b2 ... (that is if there are no multiple fields with
same names)
> Removing schema alias and :: coming from parent relation

> Customers have asked for a feature to get rid of the schema alias prefixes.
> CROSS, JOIN, FLATTEN, etc.. prepend the field name with the parent field
> alias and ::
> I would like to find a way to disable this feature. (The burden of making
> sure not to have duplicate aliases - and hence the appropriate
> FrontendException getting thrown - is on the user)
