> In MAPREDUCE-6415, we have created a CLI to har the aggregated logs, and In
> YARN-4946: RM should write out Aggregated Log Completion file flag next to
> logs, we have a discussion on how we can get the log aggregation status: make
> a client call to RM or get it directly from the Distributed file system(HDFS).
> No matter which approach we would like to choose, we need to figure out a way
> to persist the log aggregation status first. This ticket is used to track the
> working progress for this purpose.
