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

             Summary: SegmentedRaftLogReader not closed correctly
                 Key: RATIS-1634
                 URL: https://issues.apache.org/jira/browse/RATIS-1634
             Project: Ratis
          Issue Type: Bug
            Reporter: Riguz Lee


In SegmentedRaftLogInputStream#init, the SegmentedRaftLogReader instance is not correctly closed if the log is corrupted. The LogSegment#readSegmentFile function will try to delete empty segment, however it may fail on Windows because previously it's not closed.

 

This error is caught by test case

ServerRestartTests#testRestartWithCorruptedLogHeader, which fails on Windows:
