Siyao Meng created HDFS-14619:
---------------------------------
Summary: chmod changes the mask when ACL is enabled
Key: HDFS-14619
URL: https://issues.apache.org/jira/browse/HDFS-14619
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs
Affects Versions: 3.1.2
Reporter: Siyao Meng
When setting a directory's permission with HDFS shell chmod, it changes the ACL
mask instead of the permission bits:
{code:bash}
$ sudo -u impala hdfs dfs -getfacl /user/hive/warehouse/exttablename/key=1/
# file: /user/hive/warehouse/exttablename/key=1
# owner: hive
# group: hive
user::rwx
user:impala:rwx #effective:r-x
group::rwx #effective:r-x
mask::r-x
other::r-x
default:user::rwx
default:user:impala:rwx
default:group::rwx
default:mask::rwx
default:other::rwx
$ sudo -u hdfs hdfs dfs -chmod 777 /user/hive/warehouse/exttablename/key=1/
$ sudo -u impala hdfs dfs -getfacl /user/hive/warehouse/exttablename/key=1/
# file: /user/hive/warehouse/exttablename/key=1
# owner: hive
# group: hive
user::rwx
user:impala:rwx
group::rwx
mask::rwx
other::rwx
default:user::rwx
default:user:impala:rwx
default:group::rwx
default:mask::rwx
default:other::rwx
$ sudo -u hdfs hdfs dfs -chmod 755 /user/hive/warehouse/exttablename/key=1/
$ sudo -u impala hdfs dfs -getfacl /user/hive/warehouse/exttablename/key=1/
# file: /user/hive/warehouse/exttablename/key=1
# owner: hive
# group: hive
user::rwx
user:impala:rwx #effective:r-x
group::rwx #effective:r-x
mask::r-x
other::r-x
default:user::rwx
default:user:impala:rwx
default:group::rwx
default:mask::rwx
default:other::rwx
$ sudo -u impala hdfs dfs -touch /user/hive/warehouse/exttablename/key=1/file
touch: Permission denied: user=impala, access=WRITE,
inode="/user/hive/warehouse/exttablename/key=1/file":hive:hive:drwxr-xr-x
{code}
