```
public Iterable<org.apache.hadoop.fs.FileStatus> getDeletableFiles(Iterable<org.apache.hadoop.fs.FileStatus> files)
```
    Description copied from interface: FileCleanerDelegate
    
    Determines which of the given files are safe to delete
    
    Specified by:
    
    getDeletableFiles in interface FileCleanerDelegate
    
    Overrides:
    
    getDeletableFiles in class BaseFileCleanerDelegate
    
    Parameters:
    files - files to check for deletion
    
    Returns:
    files that are ok to delete according to this cleaner
  - setConf
```
