Dongwook Kwon created YARN-3929:
-----------------------------------
Summary: Uncleaning option for local app log files with
log-aggregation feature
Key: YARN-3929
URL: https://issues.apache.org/jira/browse/YARN-3929
Project: Hadoop YARN
Issue Type: New Feature
Components: log-aggregation
Affects Versions: 2.6.0, 2.4.0
Reporter: Dongwook Kwon
Priority: Minor
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.
