Description

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).
