-----------------------------------
Hi, [~Naganarasimha], Thanks for reply. The main scenario for this is to give a
way to decouple yarn with HDFS. Since nodelabel is a very important data for
yarn, if hdfs down, yarn still fail to start up. So I think this change is
meaningful for make yarn much independence when user serve both yarn and HDFS.
I make a way to beyond the zknode 1MB storage limitation. In UT, it can support
100000 nodemanager, recover all 100000 node nodelabel cost 4 seconds. It is
really efficiency and reliable.
