Jian He commented on YARN-5621:
-------------------------------
Hi [~chris.douglas], I had tried to implement with your approach. However,
this approach will not work in rollback scenario, as in that case no resources
need to be localized - hence, no need to start the localizer processes. We only
need to update the symlinks to old resources.
Overall, do you think the current approach is fine
> Support LinuxContainerExecutor to create symlinks for continuously localized
> resources

> When new resources are localized, new symlink needs to be created for the
> localized resource. This is the change for the LinuxContainerExecutor to
> create the symlinks.
