grunt> register /opt/pig-0.10.0/contrib/piggybank/java/piggybank.jar
grunt> register /opt/pig-0.10.0/build/ivy/lib/Pig/joda-time-1.6.jar
 
and also defined
 
grunt> define CustomFormatToISO  org.apache.pig.piggybank.evaluation.datetime.convert.CustomFormatToISO()  ;
grunt> define ISOToMonth  org.apache.pig.piggybank.evaluation.datetime.convert.ISOToMonth();  
 
Now I performed the query on NYSE_B.
 
grunt> describe NYSE_B;  
                                                                                    
NYSE_B: {exchange: chararray,symbol: chararray,date: chararray,divi: float}
 
ans = foreach (group NYSE_B by ISOToMonth(date)) generate group as monthh, MAX(NYSE_A.divi) as max_rt;
 
got the ERROR
