Review Comment:
bucket.listKeys() by default will return 1000 entries in each RPC. This
might be a little unnecessary as we only want to check if the directory is
empty or not here, Even if there is a single key with given prefix, it should
conclude that directory is non-empty.
1. I couldn't find an API for listKeys with maxEntries param but instead
you could use
``` java
public List<OzoneFileStatus> listStatus(String keyName, boolean recursive,
String startKey, long numEntries) throws IOException
```
and pass numEntries as 1.
3. To check if it is directory you could use `
bucket.getFileStatus(key).isDirectory();`
