Andrew Wang updated HDFS-10689:
-------------------------------
Affects Version/s: 2.6.4
Target Version/s: 3.0.0-alpha1
Hadoop Flags: Incompatible change
Description:
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

Got it, thanks Chris. Updating the JIRA fields as appropriate.
Manoj, do you mind adding a little release note about how this change will
affect end users? Could also consider changing the summary to say what this
patch will do, rather than just what is broken.
