Hi,
I' trying to compute a correlation with the script above (Pig Latin)
A = load 'input.txt' using PigStorage(':');
grp = group A all;
define c COV('a','b','c');
out = foreach grp generate group, c(A.$0,A.$1,A.$2);
the data sets is
1 2 3
4 5 6
But i get those messages
2013-06-18 01:19:58,580 [main] INFO
org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MRCompiler -

Someby could help me, please?
