zhouyingchao updated HDFS-8419:
-------------------------------
Description:
I set a directory's ACL to assign rwx permission to a user h_user1. Later, I
used chmod to change the group permission to r-x. I understand chmod of a acl
enabled file would only change the permission mask. What's make me surprise is
that the operation will change the h_user1's effective ACL from rwx to r-x.
Following are ACLs before any operaton:
-----------------------------------------
\# file: /grptest
\# owner: hdfs_tst_admin
\# group: supergroup
user::rwx
user:h_user1:rwx
group::r-x
mask::rwx
other::---
-----------------------------------------
Following are ACLs after "chmod 750 /grptest"
-----------------------------------------
\# file: /grptest
\# owner: hdfs_tst_admin
\# group: supergroup
user::rwx
user:hdfs_admin:rwx #effective:r-x
group::r-x
mask::r-x
other::---
-----------------------------------------
I'm wondering if this behavior is by design. If not, I'd like to fix the
issue. Thank you.
