CVE-2021-33036: Apache Hadoop Privilege escalation vulnerability

[Akira Ajisaka <aajisaka () apache org>]

Severity: Critical

Description:

In Apache Hadoop 2.2.0 to 2.10.1, 3.0.0-alpha1 to 3.1.4, 3.2.0 to 3.2.2, and 3.3.0 to 3.3.1, a user who can escalate to 
yarn user can possibly run arbitrary commands as root user.  Users should upgrade to Apache Hadoop 2.10.2, 3.2.3, 3.3.2 
or higher.

Mitigation:

If you are using the affected version of Apache Hadoop and some users can escalate to yarn user and cannot escalate to 
root user, remove the permission to escalate to yarn user from them.

Apache Hadoop would like to thank Hideyuki Furue for reporting and fixing this issue.
