When token is used for authentication over RPC, information other than username may be needed for access authorization. This information is typically specified in TokenIdentifier. This is especially true for block tokens used for client-to-datanode accesses, where authorization is based on access permissions specified in TokenIdentifier, and not on username. Block tokens used to be called access tokens and one can think of them as capability tokens. See
HADOOP-4359 for more info.
