[jira] [Created] (HUDI-3895) Make sure Hudi relations do proper file-split packing (on par w/ Spark)

Alexey Kudinkin created HUDI-3895:
-------------------------------------

             Summary: Make sure Hudi relations do proper file-split packing (on par w/ Spark)
                 Key: HUDI-3895
                 URL: https://issues.apache.org/jira/browse/HUDI-3895
             Project: Apache Hudi
          Issue Type: Bug
            Reporter: Alexey Kudinkin
            Assignee: Alexey Kudinkin
             Fix For: 0.11.0


While investigating on HUDI-3891, it was discovered that upon introduction of Hudi's own Spark's Relation implementations, file-split packing algorithm was inadvertently subverted: 

Spark algorithm does greedy packing which relies on the list of file-splits being ordered by the file size (descending in order).
