   > Yeah, this seems to be working around a specific resource manager in a 
corner case, I'm not sure if this is a good solution.
   
   I agree I don't like adding a config, I think it should be just globally 
changed to use the java tmp dir instead of the configured local dirs, but I 
don't know what the behavior is of k8s or standalone for how local directories 
work. I think it is currently incorrect behavior on YARN because it's using 
application level directories for executor/container specific temp files that 
should be deleted when that executor/container is finished or fails. It's not 
like shuffle data with a shuffle service that _should_ outlive the 
executor/container.
