[GitHub] [arrow-ballista] andygrove opened a new issue, #356: Use local shuffle reader in containerized environments

andygrove opened a new issue, #356:
URL: https://github.com/apache/arrow-ballista/issues/356

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   https://github.com/apache/arrow-ballista/pull/347 adds a local shuffle reader. It uses the shuffle read URL to determine if a fetch is local or not. This works well when running as standalone processes but does not work so well in a containerized environment such as k8s where multiple executors could be running on the same host but in different containers.
   
   **Describe the solution you'd like**
   Why don't we just look on disk to see if the shuffle files exist locally
   
   **Describe alternatives you've considered**
   None
   
   **Additional context**
   See discussion at https://github.com/apache/arrow-ballista/pull/347#discussion_r995794572
