Hi, I have a relation R as (a, b, c, d, e) I need to group data, but the grouping criterion is variable, depending on what input params my pig script receives. My input params are group_on_a, group_on_b, group_on_c, group_on_d which contain a value either 'T' or 'F'
so the group statement could be: A = GROUP R BY (a,b) if group_on_a and group_on_b are T and everything else is F A = GROUP R BY (a,c) if group_on_a and group_on_c are T and everything else is F A = GROUP R BY (a,b,c) if group_on_a and group_on_b, group_on_b are T and everything else is F A = GROUP R BY (a,b,c,d) and so on. Is there a way I could do this in pig ? Regards, -kunal
