Jian He commented on YARN-1406:
-------------------------------
Tested on single node cluster with 10000 finished apps (each app includes one
attempt),
HDFS store takes about 16.5 secs to recover all applications and ZooKeeper
takes about 8.5 secs.
> Check time cost for recovering max-app-limit applications

> Now that we are removing apps from state store only if we reach the
> max-completed-app-limit, In the worst case, we are recovering max-app-limit
> amount of completed applications on recovery. This is to test how cost it can
> be with ZK and hdfs state store
