> Key: HDFS-8834
> URL: https://issues.apache.org/jira/browse/HDFS-8834
> Project: Hadoop HDFS
> Issue Type: Test
> Components: datanode
> Affects Versions: 2.7.1

> Assignee: Lei (Eddy) Xu
> Priority: Minor

>
> {{TestReplication#testReplicationWhenBlockCorruption}} assumes DN has one
> level of directory:
> {code}
> File[] listFiles = participatedNodeDirs.listFiles();
> {code}
> However, HDFS-6482 changed the layout of block directories and used two level
> directories, which makes the following code invalidate (not running).
> {code}
> 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;
> }
> }
> {code}
