Greg Phillips updated YARN-5280:
--------------------------------
Attachment: YARN-5280.005.patch
Removed application queue dependency for whitelisting. Whitelisting now uses a
user group to allow users to opt out of using the JVMContainerSandbox on a job
by job basis.
Generated java.policy files are now written to the application private
directory. Users will not be able to access the policy file itself, but will
be able to inspect the policy from within the container using
System#getSecurityManager.
Container preparation functionality has been moved from
LinuxContainerExecutor#writeLaunchEnv to
LinuxContainerExecutor#prepareContainer. ContainerExecutor#prepareContainer is
called from ContainerLaunch#call prior to writeLaunchEnv. Additionally a
ContainerPrepareContext has been created as the only parameter to
ContainerExecutor#prepareContainer.

>
> 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.
