--------------------------------
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:
