-----------------------------------------
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.
