>   Original Estimate: 504h
>  Remaining Estimate: 504h
>
> Currently Hadoop KMS has implemented ACL for keys and the per key ACL are 
> stored in the configuration file kms-acls.xml.
> The management of ACL in configuration file would not be easy in enterprise 
> usage and it is put difficulties for backup and recovery.
> It is ideal to store the ACL for keys in the key meta data similar to what 
> file system ACL does.  In this way, the backup and recovery that works on 
> keys should work for ACL for keys too.
> On the other hand, with the ACL in meta data, the ACL of each key can be 
> easily manipulate with API or command line tool and take effect instantly.  
> This is very important for enterprise level access control management.  This 
> feature can be addressed by separate JIRA. While with the configuration file, 
> these would be hard to provide.
