> *Background*
> Spooling for messages is enabled for hooks that publish messages to Atlas. This is available for hooks that choose to add the following properties:
> {code:java}
> atlas.hook.spool.enabled=true
> atlas.hook.spool.dir=/spool-dir{code}
> Once the hook is initialized, the directory is created. The user who creates the directory will have read-write permissions to the spool directly.
> There are cases where the hook gets initialized with different users. When that happen, the directory is accessible to the other user. This causes initialization failure and the spooling functionality not to be available to the other user.
> *Solution(s)*
> This problem can be circumvented by making the 2 users be part of the same group that will allow for same directory to be present for multiple users. Multi-user access is currently supported.
> For the scenario, where multiple users are not part of the same group, the situation described above will come into play. 
> _Approach Used_
> **No directory exists, _User1_ first creates the directory specified in the configuration.
> Directory exists, _User1_ has access to the directory and spooling is enabled.
> Directory exists, _User2_ does not have access to the directory. New directory with username suffixed to the existing directory name is created. The directory created for the user will be
>  
> {code:java}
> /spool-dir-User1 
> {code}
