> Currently, when application is finished, NM will start to do the log
> aggregation. But for Long running service applications, this is not ideal.
> The problems we have are:
> 1) LRS applications are expected to run for a long time (weeks, months).
> 2) Currently, all the container logs (from one NM) will be written into a
> single file. The files could become larger and larger.
