> I noticed when log aggregation occurs for an application the nodemanager is
> listing the application's log directory in HDFS. Apparently this is for
> removing old logs before uploading new ones. This is a wasteful operation
> when rolling log aggregation is disabled, since there will be no prior logs
> in HDFS -- aggregation only occurs once when rolling log aggregation is
> disabled.
