Daniel Dai created PIG-5220:
-------------------------------

             Summary: Improve NestedLimitOptimizer to handle general limit push up
                 Key: PIG-5220
                 URL: https://issues.apache.org/jira/browse/PIG-5220
             Project: Pig
          Issue Type: Improvement
          Components: impl
            Reporter: Daniel Dai
            Assignee: Daniel Dai
             Fix For: 0.17.0


Currently, NestedLimitOptimizer only handles the case limit right after sort. In general, we shall push up limit recursively similar to LimitOptimizer.
