Subject [jira] [Created] (HADOOP-7987) Support setting the run-as user in unsecure mode
Date Fri, 20 Jan 2012 20:54:42 GMT
Support setting the run-as user in unsecure mode

                 Key: HADOOP-7987
                 URL: https://issues.apache.org/jira/browse/HADOOP-7987
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
    Affects Versions: 1.0.0
            Reporter: Devaraj Das
             Fix For: 1.1.0

Some applications need to be able to perform actions (such as launch MR jobs) from map or
reduce tasks. In earlier unsecure versions of hadoop (20.x), it was possible to do this by
setting user.name in the configuration. But in 20.205 and 1.0, when running in unsecure mode,
this does not work. (In secure mode, you can do this using the kerberos credentials).
