[jira] [Created] (IMPALA-7578) More flexible placement rules

Balazs Jeszenszky created IMPALA-7578:
-----------------------------------------

             Summary: More flexible placement rules
                 Key: IMPALA-7578
                 URL: https://issues.apache.org/jira/browse/IMPALA-7578
             Project: IMPALA
          Issue Type: Improvement
          Components: Frontend
    Affects Versions: Impala 3.0
            Reporter: Balazs Jeszenszky


Currently, placement rules can be defined based on user names or (primary/secondary) group names as a direct mapping. This promotes creating much more pools than might be needed, and leads to administrative overhead in when changing names or adding a new user/group.

It would be good to have a more elaborate mapping, e.g. translate user/group names into pools (including potentially mapping multiple users/groups to the same pool), either manually or via regular expressions.
