Description

JspHelper#getUGI on verifies the given token if the context and nn are set (added in HDFS-2416). We should unconditionally verifyToken the token, ie a bug where "name.node" is not set in the context object should not result in not verifying the token. In practice this shouldn't be an issue as per HDFS-3434 the context and NN should never be null.
