Tsuyoshi OZAWA commented on YARN-2052:
--------------------------------------
We can have 2 options for now:
1. Changing container Id format. ContainerId should be an opaque string that
YARN app developers don't take a dependency on.
2. Preserving container Id format. RM restart Phase 2 should be transparent
from YARN users.
> Container ID format and clustertimestamp for Work preserving restart
