[jira] [Created] (SPARK-38605) Retrying on file manager operation in HDFSMetadataLog

L. C. Hsieh created SPARK-38605:
-----------------------------------

             Summary: Retrying on file manager operation in HDFSMetadataLog
                 Key: SPARK-38605
                 URL: https://issues.apache.org/jira/browse/SPARK-38605
             Project: Spark
          Issue Type: Improvement
          Components: Structured Streaming
    Affects Versions: 3.4.0
            Reporter: L. C. Hsieh


Currently HDFSMetadataLog uses CheckpointFileManager to do some file operation like opening metadata file. It is very easy to be affected by network blips and causes the streaming query failed. Although we can restart the streaming query, but it takes more time to recover.

Such file operations should be resilient with such situation by retrying.
