             Summary: Missing ACL on implicitly created partitions
                 Key: IMPALA-7649
                 URL: https://issues.apache.org/jira/browse/IMPALA-7649
             Project: IMPALA
          Issue Type: Bug
            Reporter: Zsolt Herczeg


If a partition is created via alter table, Impala will apply the ACL (group:hive:rwx) to the partition folder to ensure compatibility with HiveServer2.

In case a partition is created implicitly, during an INSERT query, this ACL is not applied, causing interoperability issues.

Steps to reproduce:
{code:java}
CREATE EXTERNAL TABLE test (a int) PARTITIONED BY (y int) STORED AS TEXTFILE LOCATION '/user/admin/test/';
ALTER TABLE test ADD PARTITION (y=1);
INSERT INTO test (a) PARTITION (y=2) VALUES (2);{code}
Resulting ACLs are:
{code:java}
hdfs dfs -getfacl /user/admin/test/
# file: /user/admin/test
# owner: impala
# group: admin
user::rwx
group::rwx
group:hive:rwx
mask::rwx
other::rwx
hdfs dfs -getfacl /user/admin/test/y=1
# file: /user/admin/test/y=1
# owner: impala
# group: admin
user::rwx
group::rwx
group:hive:rwx
mask::rwx
other::rwx
hdfs dfs -getfacl /user/admin/test/y=2
# file: /user/admin/test/y=2
# owner: impala
# group: admin
user::rwx
group::r-x
other::r-x{code}
