Jason Lowe commented on YARN-3476:
----------------------------------
bq. Such cases we can use the aggregated log-retention configuration i.e
'yarn.log-aggregation.retain-seconds' for deleting from disk.
No, that's not going to be OK. One is the lifetime on the aggregation
filesystem and what we're considering is the lifetime on the local disk. I can
hold a lot more logs in HDFS than I can in the local disk.
> Nodemanager can fail to delete local logs if log aggregation fails
