             Summary: POReservoirSample should handle endOfAllInput flag
                 Key: PIG-3786
                 URL: https://issues.apache.org/jira/browse/PIG-3786
             Project: Pig
          Issue Type: Sub-task
          Components: tez
    Affects Versions: tez-branch
            Reporter: Daniel Dai
            Assignee: Daniel Dai
             Fix For: tez-branch


POReservoirSample assumes it always get STATUS_OK until it hits STATUS_EOP, means all inputs finished. This is not true if the plan also contains a POStream, since POStream will issue a STATUS_EOP even if inputs are not exhausted. Need to make POReservoirSample handles STATUS_EOP and endOfAllInput flag. This cause e2e test failure such as ComputeSpec_3.

POPoissonSample should do the same.
