> Key: HDFS-10689
> URL: https://issues.apache.org/jira/browse/HDFS-10689
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: fs
> Affects Versions: 2.6.4
> Reporter: Manoj Govindassamy
> Assignee: Manoj Govindassamy
> Priority: Minor
> Attachments: HDFS-10689.001.patch, HDFS-10689.002.patch,

>
> 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
> {noformat}
