In 2nd line -
1. It is missing the identifier for the name of new relation (B = )
2. What you have is a bag of tuples of type integer. The number of instances
of the tuple in the bag does not matter for the schema (like array type in
java - int [] aa;)
Changing it to following should work -
B = FOREACH A GENERATE (bag{tuple(long)})aa;
