Today when node manager restarts we clean up all the distributed cache files from disk. This is definitely not ideal from 2 aspects.
- For work preserving restart we definitely want them as running containers are using them
- For even non work preserving restart this will be useful in the sense that we don't have to download them again if needed by future tasks.
