org.apache.pig.builtin.COR
Computes the correlation between sets of data. The returned value will be a bag which will contain a tuple for each combination of input schema and inside tuple we will have two schema name and correlation between those two schemas. A = load 'input.xml' using PigStorage(':');
B = group A all;
D = foreach B generate group,COR(A.$0,A.$1,A.$2);
