Mingliang Liu commented on HDFS-9672:
-------------------------------------
Suppose the {{LeaseManager$Monitor}} is doing blocking I/O via: {{run() ->
FSEditLog#logSync() -> EditLogOutputStream#flush() -> JournalSet#flushAndSync()
-> JournalSet#mapJournalsAndReportErrors()}}, if there is an
InterruptException, the channel will be closed and the journals will be
disabled via {{disableAndReportErrorOnJournals()}}. The test main thread then
closes the edit log because of {{MiniDFSCluster#restartNameNode()}}. During the
closing process, it will call {{FSEditLog#endCurrentLogSegment()}} which calls
{{FSEditLog#logSync()}} internally. At the point, the {{logSync()}} will fail
because all the journals are disabled; the {{System#exit()}} will be called
immediately. This may be a potential bug which happens when the NN is stopping
all active services.
Normally, the in-progress edit log would be finalized by
{{FSEditLog#endCurrentLogSegment}}. For testing purposes, we can disable that
here.
