zhangyubiao commented on YARN-5955:

[~templedf]´╝îis it zookeeper is the best way to store the app state? is it can improve performance
to the large cluster to 
recovery apps?
 as we [~tangshangwen] [~zhengchenyu] see in  http://www.slideshare.net/arinto/next-generation-hadoop-high-availability-for-yarn.
 it seem like that zookeeper is not the best way to store the app state.
