> The 'owner' of any delegation token issued by the MetaStore is set to the
> requesting user. When a delegation token is asked by the user himself during
> a job submission, this is fine. However, in the case where the token is
> requested for by services (e.g., Oozie), on behalf of the user, the token's
> owner is set to the user the service is running as. Later on, when the token
> is used by a MapReduce task, the MetaStore treats the incoming request as
> coming from Oozie and does operations as Oozie. This means any new directory
> creations (e.g., create_table) on the hdfs by the MetaStore will end up with
> Oozie as the owner.
> Also, the MetaStore doesn't check whether a user asking for a token on behalf
> of some other user, is actually authorized to act on behalf of that other
> user. We should start using the ProxyUser authorization in the MetaStore
> (HADOOP-6510's APIs).
