### Description of PR
I found that PublicLocalizer is exiting, because of the /tmp directory was
deleted by mistake, then throw NPE, then causing spark job to be stuck.
[YARN-9968](https://issues.apache.org/jira/browse/YARN-9968) have resolve
the NPE problem. For me, I think when the `PublicLocalizer` thread exits, the
NM should be shut down, because there is no point in keeping an abnormal NM
running.
### How was this patch tested?
manual test
### For code changes:
- [x] When PublicLocalizer is exiting, shutdown the NodeManager.
> NodeManager should shutdown when PublicLocalizer is exiting.
