Hi I am very neophyte to hadoop and when I first run this command LOAD 'Pig/iris.csv' using PigStorage (',') the error popped out:
LOAD 'Pig/iris.csv' using PigStorage (',');

Does anyone know how to solve the problem?
LOAD creates a relation. You need to assign that to a variable so that you can do something with it later:
L = LOAD 'Pig/iris.csv' using PigStorage (',');
DUMP L;
