Description

TestReplication#testReplicationWhenBlockCorruption assumes DN has one level of directory:

File[] listFiles = participatedNodeDirs.listFiles();

However, HDFS-6482 changed the layout of block directories and used two level directories, which makes the following code invalidate (not running).

for (File file : listFiles) {
  if (file.getName().startsWith(Block.BLOCK_FILE_PREFIX)
      && !file.getName().endsWith("meta")) {
      blockFile = file.getName();
      for (File file1 : nonParticipatedNodeDirs) {
        file1.mkdirs();
        new File(file1, blockFile).createNewFile();
        new File(file1, blockFile + "_1000.meta").createNewFile();
      }
    break;
    }
 }
