-------------------------------

             Summary: Hive streaming source should use FIFO FileSplitAssigner 
instead of LIFO
                 Key: FLINK-21905
                 URL: https://issues.apache.org/jira/browse/FLINK-21905
             Project: Flink
          Issue Type: Sub-task
          Components: Connectors / Hive
            Reporter: Jark Wu


Currently, Hive streaming source uses {{SimpleAssigner}} which hands out splits 
in LIFO order. However, it will result in out-of-order partition reading even 
if we add partition splits in order. Therefore, we should use a FIFO order 
{{FileSplitAssigner}} instead.
