Subject [jira] Commented: (HADOOP-6661) User document for UserGroupInformation.doAs
Date Thu, 03 Jun 2010 23:01:54 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6661?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12875342#action_12875342

Jakob Homan commented on HADOOP-6661:

I'm not wild about the use of Oozie in the example.  Oozie's not yet in the code source and
there's no reason documentation readers would be familiar with that project.  Also, the text
makes it sound as if this feature is in there for Oozie in particular.  There needs to be
more explanation that this is a generic feature for different types of superusers.  Also,
this is the only place we use the term "Secure Impersonation," which sounds like a poor word
choice.  What about "Superusers submitting jobs on behalf of other users"?
