> 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.
