Hi, Chan:
I guess you might generate the bag like this
A = load 'test.txt' as (f1:chararray,f2:chararray,f3:chararray);
B = group A by f1;
C = foreach B generate *;
describe C;
C: {group: chararray,{(f1: chararray)},{(f2: chararray)},{(f3: chararray)}}
if this is the case, you can do:
A = load 'test.txt' as (f1:chararray,f2:chararray,f3:chararray);
B = group A by f1;
C = foreach B generate group, A.f1, A.f2;
describe C;
C: {group: chararray,{(f1: chararray)},{(f2: chararray)}}
does this make sense? otherwise can you share your script which generates
the bag?
