Does this configuration: yarn.nodemanager.delete.debug-delay-sec satisfy your requirement ?

> Although it makes sense to delete local app log files once AppLogAggregator copied all files into remote location(HDFS), I have some use cases that need to leave local app log files after it's copied to HDFS. Mostly it's for own backup purpose. I would like to use log-aggregation feature of YARN and want to back up app log files too. Without this option, files has to copy from HDFS to local again.
