[jira] [Created] (PIG-4149) Rounding issue in FindQuantiles

Daniel Dai created PIG-4149:
-------------------------------

             Summary: Rounding issue in FindQuantiles
                 Key: PIG-4149
                 URL: https://issues.apache.org/jira/browse/PIG-4149
             Project: Pig
          Issue Type: Bug
          Components: impl
            Reporter: Daniel Dai
            Assignee: Daniel Dai
             Fix For: 0.14.0


In FindQuantiles, Pig calculates an integer toSkip inside sample, and skip "toSkip" sample records to find the next boundary. However, toSkip should not be an integer, this will cause rounding issue and all the remainder will goes to the last partition.
