shrutig opened a new pull request #25514: [SPARK-28784]StreamExecution and 
StreamingQueryManager should utilize CheckpointFileManager to interact with 
checkpoint directories
URL: https://github.com/apache/spark/pull/25514
 
 
   ### What changes were proposed in this pull request?
   After PR https://github.com/apache/spark/pull/21048, the 
CheckpointFileManager interface was created to handle all structured streaming 
checkpointing operations and helps users to choose how they wish to write 
checkpointing files atomically.
   StreamExecution and StreamingQueryManager still uses some FileSystem 
operations without using the CheckpointFileManager.
   For instance,
   
https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/StreamExecution.scala#L137
   
https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/StreamExecution.scala#L392
   
   Instead, StreamExecution and StreamingQueryManager should use 
CheckpointFileManager for these operations.
   
   ### Why are the changes needed?
   This change will allow users to use CheckpointFileManager for structured 
streaming checkpointing files without need for a separate FileSystem 
implementation for the same.
   
   
   ### Does this PR introduce any user-facing change?
   No
   
   ### How was this patch tested?
   Existing tests
