> Make Schedulables return a configurable identity of user or group
> -----------------------------------------------------------------

> Key: HADOOP-10280
> URL: https://issues.apache.org/jira/browse/HADOOP-10280
> Project: Hadoop Common
> Issue Type: Sub-task

> Attachments: HADOOP-10280.patch, HADOOP-10280.patch,

> In order to intelligently schedule incoming calls, we need to know what
> identity it falls under.
> We do this by defining the Schedulable interface, which has one method,
> getIdentity(IdentityType idType)
> The scheduler can then query a Schedulable object for its identity, depending
> on what idType is.
> For example:
> Call 1: Made by user=Alice, group=admins
> Call 2: Made by user=Bob, group=admins
> Call 3: Made by user=Carlos, group=users
> Call 4: Made by user=Alice, group=admins
> Depending on what the identity is, we would treat these requests differently.
> If we query on Username, we can bucket these 4 requests into 3 sets for
> Alice, Bob, and Carlos. If we query on Groupname, we can bucket these 4
> requests into 2 sets for admins and users.
> In this initial version, idType can be username or primary group. In future
> versions, it could be jobID, request class (read or write), or some explicit
> QoS field. These are user-defined, and will be reloaded on callqueue refresh.
