> YARN applications have the ability to perform privileged actions which have the potential
to add instability into the cluster. The Java Security Manager can be used to prevent users
from running privileged actions while still allowing their core data processing use cases.

> Introduce a YARN flag which will allow a Hadoop administrator to enable the Java Security
Manager for user code, while still providing complete permissions to core Hadoop libraries.
