> 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).
