[jira] [Created] (IMPALA-6598) Investigate memory requirement regression from scanner buffer pool change

Tim Armstrong created IMPALA-6598:
-------------------------------------

             Summary: Investigate memory requirement regression from scanner buffer pool change
                 Key: IMPALA-6598
                 URL: https://issues.apache.org/jira/browse/IMPALA-6598
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 3.0, Impala 2.12.0
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong


We should determine if the increase memory requirements on some queries (e.g. IMPALA-6585) can be avoided or whether they're severe enough to justify backing out the scanner memory usage changes.
