[jira] [Updated] (IMPALA-7649) Missing ACL on implicitly created
partitions
[ https://issues.apache.org/jira/browse/IMPALA-7649?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Zsolt Herczeg updated IMPALA-7649:
----------------------------------
Description:
If a partition is created via ALTER TABLE, Impala will apply an 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}
