Hi yarn-dev, I am trying to understand the extent to which the NMs support retaining application related cache.
“yarn.nodemanager.delete.debug-delay-sec” can be used to control the number of seconds after an application finishes before the NM's DeletionService will delete the application's localized file directory and log directory. Is there a way to control the retention period for the localized file directory independent of the log directory ? That is, if I want to retain certain application data longer than the log's retention, is there a way to do it in YARN ? Thanks! Navina
