> Components: log-aggregation, nodemanager
> Reporter: Xu Yang

> Before Hadoop 2.6, the LogAggregationService is started in NodeManager. But the AggregatedLogDeletionService is started in mapreduce`s JobHistoryServer. Therefore, the Non-MapReduce application can aggregate their logs to HDFS, but can not delete those logs. Need the NodeManager take over the function of aggregated log deletion.
