    [CELEBORN-728] Celeborn won't clean remnant application directory on HDFS if worker is restarted
    
    ### What changes were proposed in this pull request?
    To clean the remnant application directory after Celeborn Worker is restarted.
    
    ### Why are the changes needed?
    Remnant application directories will not be deleted, because `hadoopFs.listFiles(path,false)` will not list directories.
    
    ### Does this PR introduce _any_ user-facing change?
    No.
    
    Closes #1641 from Demon-Liang/0.3-dev.
