Review Comment:
I'm surprise that `Thread.sleep()` works fine but
[GenericTestUtils#waitFor](https://github.com/apache/ozone/blob/387c53781aae03f944906a0add58f51250d36687/hadoop-hdds/test-utils/src/main/java/org/apache/ozone/test/GenericTestUtils.java#L214)
doesn't. Just curious what was lambda used?
I feel this should work if it is just about cleaning dir.
```
GenericTestUtils.waitFor(() -> {
try {
FileStatus[] fileStatus = fs.listStatus(ROOT);
return fileStatus != null && fileStatus.length == 0;
} catch (IOException e) {
return false;
}
}, 100, 500);
```
