> Improve container-executor validation check

> Key: YARN-7590
> URL: https://issues.apache.org/jira/browse/YARN-7590
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: security, yarn
> Affects Versions: 2.0.1-alpha, 2.2.0, 2.3.0, 2.4.0, 2.5.0, 2.6.0, 2.7.0,
> 2.8.0, 2.8.1, 3.0.0-beta1

>
> There is minimum check for prefix path for container-executor. If YARN is
> compromised, attacker can use container-executor to change system files
> ownership:
> {code}
> /usr/local/hadoop/bin/container-executor spark yarn 0 etc /home/yarn/tokens
> /home/spark / ls
> {code}
> This will change /etc to be owned by spark user:
> {code}
> # ls -ld /etc
> drwxr-s---. 110 spark hadoop 8192 Nov 21 20:00 /etc
> {code}
> Spark user can rewrite /etc files to gain more access. We can improve this
> with additional check in container-executor:
> # Make sure the prefix path is owned by the same user as the caller to
> container-executor.
> # Make sure the log directory prefix is owned by the same user as the caller.
