Allen Wittenauer commented on HADOOP-13109:
-------------------------------------------
Hindsight 20/20, but I'm sort of regretting how the term 'alias' was used in
dtutil. Oh well.
+1. Thanks!
I'll commit this trunk here in a bit.

> The first iteration of the dtutil command
> (org.apache.hadoop.security.token.DtUtilShell) did not provide an operation
> to edit the service field on a token that has already been fetched to a file.
> This is a necessary feature for users who have copied a token file out of a
> cluster that does not support the dtutil command (hence, the token could not
> be aliased during get).
