[~Steven Rand] I'm unable to attach patch files to this ticket either.  Maybe you can post
a link to public github gist instead?

> 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.
