             Summary: Ozone: Put key operation concurrent executes failed on Windows
                 Key: HDFS-12565
                 URL: https://issues.apache.org/jira/browse/HDFS-12565
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
    Affects Versions: HDFS-7240
            Reporter: Yiqun Lin


When creating a batch size of key under specified bucket, then the error happens on Windows. This error was found by executing {{TestOzoneShell#testListKey()}}.

The related codes(ChunkUtils#writeData):
{code}
 public static void writeData(File chunkFile, ChunkInfo chunkInfo,
      byte[] data) throws
      StorageContainerException, ExecutionException, InterruptedException,
      NoSuchAlgorithmException {
    ...

    try {
      file =
          AsynchronousFileChannel.open(chunkFile.toPath(),
              StandardOpenOption.CREATE,
              StandardOpenOption.WRITE,
              StandardOpenOption.SPARSE,
              StandardOpenOption.SYNC);
      lock = file.lock().get();
      if (chunkInfo.getChecksum() != null &&
          !chunkInfo.getChecksum().isEmpty()) {
        verifyChecksum(chunkInfo, data, log);
      }
      int size = file.write(ByteBuffer.wrap(data), chunkInfo.getOffset()).get();
      if (size != data.length) { <===== error was thrown
        log.error("Invalid write size found. Size:{}  Expected: {} ", size,   
            data.length);
        throw new StorageContainerException("Invalid write size found. " +
            "Size: " + size + " Expected: " + data.length, INVALID_WRITE_SIZE);
      }
...
{code}
But if we only put one single key, it runs well.
