bin/hadoop fs -chmod doesnot change execution permissions for files.
--------------------------------------------------------------------

                 Key: HADOOP-3078
                 URL: https://issues.apache.org/jira/browse/HADOOP-3078
             Project: Hadoop Core
          Issue Type: Bug
    Affects Versions: 0.16.0
            Reporter: Amareshwari Sriramadasu



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
