Jun Gong updated YARN-3161:
---------------------------
Description:
When RM restart, containers' information will be lost for the following
scenarios:
1. NM restarts before it sends containers' information to the new active RM.
2. NM stops and it could not send containers' information to the new active RM.
Without those containers' information, corresponding AM will never get their
status through RM, and AM would just wait them for ever.
