[jira] [Created] (IMPALA-5254) Take Kudu partitioning into account when deciding to repartition

Thomas Tauber-Marshall created IMPALA-5254:
----------------------------------------------

             Summary: Take Kudu partitioning into account when deciding to repartition
                 Key: IMPALA-5254
                 URL: https://issues.apache.org/jira/browse/IMPALA-5254
             Project: IMPALA
          Issue Type: Improvement
          Components: Frontend
    Affects Versions: Impala 2.9.0
            Reporter: Thomas Tauber-Marshall
            Assignee: Thomas Tauber-Marshall


A change that's about to go in (IMPALA-3742) adds partitioning of inserts into Kudu tables that matches the partitioning scheme of the table.

As is, the patch will always repartition inserts that are sufficiently large, but we should improve this to not repartition if the input is already partitioned correctly.
