Manoj Govindassamy created HDFS-10689:
-----------------------------------------
Summary: "hdfs dfs -chmod 777" does not remove sticky bit
Key: HDFS-10689
URL: https://issues.apache.org/jira/browse/HDFS-10689
Project: Hadoop HDFS
Issue Type: Bug
Components: fs
Reporter: Manoj Govindassamy
Assignee: Manoj Govindassamy
Priority: Minor
When a directory permission is modified using hdfs dfs chmod command and when
octal/numeric format is used, the leading sticky bit is not fully honored.
1. Create a dir dir_test_with_sticky_bit
2. Apply sticky bit permission on the dir : hdfs dfs -chmod 1755
/dir_test_with_sticky_bit
3. Remove sticky bit permission on the dir: hdfs dfs -chmod 755
/dir_test_with_sticky_bit
Expected: Remove the sticky bit on the dir, as it happens on Mac/Linux native
filesystem with native chmod.
4. However, removing sticky bit permission by explicitly turning off the bit
works. hdfs dfs -chmod 0755 /dir_test_with_sticky_bit
