Hi,
I'm working on a custom Loader and for one of the usecases I want to be
able to return a typed map. So essentially a map where each element has a
specific schema (tuple/bag).
I.e. something like this:
http://pig.apache.org/docs/r0.13.0/basic.html#map-schema
b = stream a through `cat` as (m:*map[{(i:int,j:chararray)}]*); -- Map
value is bag
Possibly I will need a deeper nesting level (i.e. tuple in a bag in a bag).
What I am looking for is preferably an existing opensource Loader that does
this so I can see which API methods must be called where to achieve this
correctly.
Thanks.
