> Webhdfs passes {{UserParam}} even when a token is being used. The NN will
> construct the UGI from the token and error if the {{UserParam}} does not
> match the token's. This causes problems when a token for user A is used with
> user B's context. This is in contrast to hdfs which will honor the token's
> ugi no matter the client's current context. The passing of a token or user
> params should be mutually exclusive.
