Subject [jira] [Created] (HDFS-2281) NPE in checkpoint during processIOError()
Date Wed, 24 Aug 2011 01:21:29 GMT
NPE in checkpoint during processIOError()
-----------------------------------------

                 Key: HDFS-2281
                 URL: https://issues.apache.org/jira/browse/HDFS-2281
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.22.0
            Reporter: Konstantin Shvachko
             Fix For: 0.22.0


At the end of checkpoint BackupNode tries to convergeJournalSpool() and calls revertFileStreams().
The latter closes each file stream, and tries to rename the corresponding file to its permanent
location current/edits. If for any reason the rename fails processIOError() is called for
failed streams. processIOError() will try to close the stream again and will get NPE in EditLogFileOutputStream.close()
because bufCurrent was set to null by the previous close.
