Tsz Wo (Nicholas), SZE commented on HADOOP-3078:
------------------------------------------------
>At the least, it is confusing to the user. 'x' is something user sets (unlike
>'d'), I wonder why it is disallowed for files in HDFS.
In Hadoop, all files are non-executable (which is different from Unix). So
there is no 'x' bit.
> 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
