[jira] [Created] (SPARK-35240) Use CheckpointFileManager for checkpoint manipulation

L. C. Hsieh created SPARK-35240:
-----------------------------------

             Summary: Use CheckpointFileManager for checkpoint manipulation
                 Key: SPARK-35240
                 URL: https://issues.apache.org/jira/browse/SPARK-35240
             Project: Spark
          Issue Type: Improvement
          Components: Structured Streaming
    Affects Versions: 3.2.0
            Reporter: L. C. Hsieh
            Assignee: L. C. Hsieh


`CheckpointFileManager` is designed to handle checkpoint file manipulation. However, there are a few places exposing FileSystem from checkpoint files/paths. We should use `CheckpointFileManager` to manipulate checkpoint files. For example, we may want to have one storage system for checkpoint file. If all checkpoint file manipulation is performed through `CheckpointFileManager`, we can only implement `CheckpointFileManager` for the storage system, and don't need to implement FileSystem API for it.
