TryBelow:-
A = load 'ngt/ngt.csv' using PigStorage('\t') as(ngram:chararray,
year:int,mc:int,pc:int,vc:int);
B = group A by ngram;
C = foreach B generate group, COUNT(A);
store C into 'ngout/out.txt' using PigStorage('\t');

I think the problem is with the COUNT( ngram) invoked with a chararray

Thanks
