Subject [jira] [Created] (YARN-1853) Allow containers to be ran under real user even in insecure mode
Date Wed, 19 Mar 2014 15:04:47 GMT
Andrey Stepachev created YARN-1853:
--------------------------------------

             Summary: Allow containers to be ran under real user even in insecure mode
                 Key: YARN-1853
                 URL: https://issues.apache.org/jira/browse/YARN-1853
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
            Reporter: Andrey Stepachev


Currently unsecure cluster runs all containers under one user (typically nobody). That is
not appropriate, because yarn applications doesn't play well with hdfs having enabled permissions.
Yarn applications try to write data (as expected) into /user/nobody regardless of user, who
launched application.

Another sideeffect is that it is not possible to configure cgroups for particular users.
