Subject [jira] [Commented] (HADOOP-8561) Introduce HADOOP_PROXY_USER for secure impersonation in child hadoop client processes
Date Thu, 05 Jul 2012 13:53:35 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13407112#comment-13407112
] 

Robert Joseph Evans commented on HADOOP-8561:
---------------------------------------------

This would be really good for testing as well.  We have seen issues with HFTP tokens being
broken only for proxy users, but were not testing it properly.  This should make that testing
a lot simpler in the future.  +1 for the idea.

> To solve the problem for an authenticated user to type hadoop shell commands in a web
console, we can introduce an HADOOP_PROXY_USER environment variable to allow proper impersonation
in the child hadoop client processes.
