Richard Ding commented on PIG-1514:
-----------------------------------
Patch looks good. A couple of comments:
* It would be better to refactor the graph manipulation code into a helper
class so that the graph transformation routines (such as swap, insert, remove,
replace, ...) can be shared by all rules.
* Please remove tabs from the file.
> Migrate logical optimization rule: OpLimitOptimizer
