Yuan Tian created IOTDB-1427:
--------------------------------

             Summary: Compaction may delete some tsfiles are being queried
                 Key: IOTDB-1427
                 URL: https://issues.apache.org/jira/browse/IOTDB-1427
             Project: Apache IoTDB
          Issue Type: Bug
          Components: Core/Engine
            Reporter: Yuan Tian
            Assignee: Yuan Tian


When Level compaction is ending(delete file in resource list and delete file in disk). The query may get a tsfile resource from resource list. However, it may be deleted by the compaction ending process later, then the query process cannot read data from the deleted resource. Which may cause a ci problem like below.
