-----------------------------------------
Hi [~yxls123123]
bq. The Non-MapReduce application can aggregate their logs to HDFS, but can not
delete those logs
You mean in secure environment Non-MapReduce application cannot delete the logs
? basically why not, application specific History server handle this deletion ?
or you have Non-MapReduce application which doesnt have a daemon service (like
history server) running ?
> YARN should support to delete the aggregated logs for Non-MapReduce
> applications

> Key: YARN-2985
> URL: https://issues.apache.org/jira/browse/YARN-2985
> Project: Hadoop YARN
> Issue Type: New Feature
> 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.
