Xuan Gong updated YARN-2468:
----------------------------
Description:
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.
> Log handling for LRS
