> When a log aggregation fails on the NM the information is for the attempt is
> kept in the recovery DB. Log aggregation can fail for multiple reasons which
> are often related to HDFS space or permissions.
> On restart the recovery DB is read and if an application attempt needs its
> logs aggregated, the files are scheduled for aggregation without any checks.
> The log files could be older than the retention limit in which case we should
> not aggregate them but immediately mark them for deletion from the local file
> system.
