--------------------------------------
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.
