----------------------------------

             Summary: DataRegion snapshot may meet file not found due to 
compaction
                 Key: IOTDB-3344
                 URL: https://issues.apache.org/jira/browse/IOTDB-3344
             Project: Apache IoTDB
          Issue Type: Bug
            Reporter: Jialin Qiao
            Assignee: Liuxuxin


When do snapshot in data region, we just list files in each folder and then do 
hard link.

If the compaction delete some file just between list file and do hard link, an 
exception will occur.

 

We need to get tsfiles from TsFileManager.
