Summary: Consolidate ACL inheritance
Key: IMPALA-7695
URL: https://issues.apache.org/jira/browse/IMPALA-7695
Project: IMPALA
Issue Type: Improvement
Reporter: Zsolt Herczeg
As of now Impala behavior is not consistent regarding ACL inheritance by
default.
If --insert_inherit_permissions is not specified, then:
{code:java}
CREATE EXTERNAL TABLE acl_test (a int) partitioned by (b int) STORED AS PARQUET
LOCATION '/dataroot/acl_test/';
{code}
This will create the table directory (/dataroot/acl_test), and inherit the
parent dir (/dataroot) acls.
{code:java}
ALTER TABLE acl_test ADD PARTITION (b=10)
{code}
This will create the partition directory (/dataroot/acl_test/b=10) and inherit
the parent dir (/dataroot/acl_test) acls.
{code:java}
INSERT INTO acl_test (a,b) VALUES (1,2)
{code}
This will create the partition directory (/dataroot/acl_test/b=2) but will
*not* inherit any acls.
The difference in the INSERT/ALTER behavior will lead to inconsistent partition
directory permissions, depending on whether they were created explicitly
beforhand or implicitly during an insert.
This is documented, but generally unexpected. I'd recommend to review if a more
consistent approach could be followed for ACLs on partition directories..
