Log aggregation performs extraneous filesystem operations when rolling log aggregation is disabled

      Description

      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.
