PIG how to count a number of rows in alias

Question

I did something like this to count the number of rows in an alias in PIG:

logs = LOAD \'log\'
logs_w_one = foreach logs generate 1 as one;
logs_group = group         


        

Answer 1

Be careful, with COUNT your first item in the bag must not be null. Else you can use the function COUNT_STAR to count all rows.
