Xuan Gong commented on YARN-1879:
---------------------------------
+1 on Jian's proposal. We need to handle this scenario in failover/restart. But
the Retry-cache method can not fully solve this problem. Handling it on RM side
sounds like a better idea. We did similar things before, such as
submitApplication.
