Shravan Matthur Narayanamurthy commented on PIG-402:
----------------------------------------------------
This is what I have understood - Comparators in Hadoop assume that you know the
type of key(keyClass) beforehand and do not let you configure the type
dynamically. So I feel, the only way out for us is to wrap the key inside a
tuple whenever, a User Defined Comparison Func is used.
If any of you have other suggestions, please comment.
