> Adding service-level authorization to Hadoop

> Service-level authorization is the initial checking done by a Hadoop service
> to find out if a connecting client is a pre-defined user of that service. If
> not, the connection or service request will be declined. This feature allows
> services to limit access to a clearly defined group of users. For example,
> service-level authorization allows "world-readable" files on a HDFS cluster
> to be readable only by the pre-defined users of that cluster, not by anyone
> who can connect to the cluster. It also allows a M/R cluster to define its
> group of users so that only those users can submit jobs to it.
> Here is an initial list of requirements I came up with.
> 1. Users of a cluster is defined by a flat list of usernames and groups.
> A client is a user of the cluster if and only if her username is listed in
> the flat list or one of her groups is explicitly listed in the flat list.
> Nested groups are not supported.
> 2. The flat list is stored in a conf file and pushed to every cluster
> node so that services can access them.
> 3. Services will monitor the modification of the conf file periodically
> (5 mins interval by default) and reload the list if needed.
> 4. Checking against the flat list is done as early as possible and before
> any other authorization checking. Both HDFS and M/R clusters will implement
> this feature.
> 5. This feature can be switched off and is off by default.
> I'm aware of interests in pulling user data from LDAP. For this JIRA, I
> suggest we implement it using a conf file. Additional data sources may be
> supported via new JIRA's.
