             Summary: VolumeScanner prints incorrect IOException in reportBadBlocks operation
                 Key: HDFS-10626
                 URL: https://issues.apache.org/jira/browse/HDFS-10626
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Yiqun Lin
            Assignee: Yiqun Lin


VolumeScanner throws incorrect IOException in {{datanode.reportBadBlocks}}. The related codes:
{code}
    public void handle(ExtendedBlock block, IOException e) {
      FsVolumeSpi volume = scanner.volume;
      ...
      try {
        scanner.datanode.reportBadBlocks(block, volume);
      } catch (IOException ie) {
        // This is bad, but not bad enough to shut down the scanner.
        LOG.warn("Cannot report bad " + block.getBlockId(), e);
      }
    }
{code}
The IOException that printed in the log should be {{ie}} rather than {{e}} which was passed in method {{handle(ExtendedBlock block, IOException e)}}.
