Chris Trezzo commented on YARN-5027:
------------------------------------

Does the current patch have the potential to leak {{application_*_*_DEL_*}} 
directories? In {{ResourceLocalizationService#cleanupLogDir}} would we want to 
check if the renamed _DEL_ directory exists in the case where the original log 
directory doesn't exist and delete if necessary?

> NM should clean up app log dirs after NM restart
