[jira] Resolved: (HADOOP-3078) bin/hadoop fs -chmod doesnot change
execution permissions for files.
[ https://issues.apache.org/jira/browse/HADOOP-3078?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Chansler resolved HADOOP-3078.
-------------------------------------
Resolution: Invalid
Files do not have an execute permission. (Directories _do_ have an execute permission.)
>From the user guide:
" In contrast to the POSIX model, there are no sticky, setuid
or setgid bits for files as there is no notion of executable files."
> bin/hadoop fs -chmod doesnot change execution permissions for files.

> bin/hadoop fs -chmod doesnt change execution permissions for files.
> I have two files in scripts directory
> $ hadoop fs -lsr scripts
> /user/amarsri/scripts/my.pl <r 3> 146 2008-03-24 14:39 rw-r--r-- amarsri supergroup
> /user/amarsri/scripts/xyz.pl <r 3> 146 2008-03-24 14:39 rw-r--r-- amarsri supergroup
> When i ran -chmod 777 on the file, file has only read permissions but no execution permissions.
> $ hadoop fs -chmod 777 /user/amarsri/scripts/my.pl
> $ hadoop fs -lsr scripts
> /user/amarsri/scripts/my.pl <r 3> 146 2008-03-24 14:39 rw-rw-rw- amarsri supergroup
> /user/amarsri/scripts/xyz.pl <r 3> 146 2008-03-24 14:39 rw-r--r-- amarsri supergroup
> When I do -chmod -R 777 on the directory, permissions are given to the directory, and the directories inside them, but files dont get execution permissions.
> $ hadoop fs -chmod -R 777 /user/amarsri/scripts/
> $ hadoop fs -lsr scripts
> /user/amarsri/scripts/my.pl <r 3> 146 2008-03-24 14:39 rw-rw-rw- amarsri supergroup
> /user/amarsri/scripts/xyz.pl <r 3> 146 2008-03-24 14:39 rw-rw-rw- amarsri supergroup
> "$hadoop fs -ls" lists scripts as the following.
> /user/amarsri/scripts <dir> 2008-03-24 14:39 rwxrwxrwx amarsri supergroup
