             Summary: Add ability to edit existing token file via dtutil -alias 
flag 
                 Key: HADOOP-13109
                 URL: https://issues.apache.org/jira/browse/HADOOP-13109
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Matthew Paduano
            Assignee: Matthew Paduano
            Priority: Minor


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).
