Daniel Dai commented on PIG-5223:
---------------------------------
mlimitplan is an expression to calculate limit variable. That is, the number of
limited rows is determined at runtime by evaluation expressionPlan (the
physical plan equivalence of mlimitplan). If (mLimit == -1 && mlimitPlan !=
null), that means limiting by variable not constant. It is basically the same
as your (mLimit = -1) condition, but add another condition for assurance.
