Review comment: I think the state will either be on zk or on hdfs? HMaster itself is state less... In general, in the current architecture, I think it the state should be placed on zk, of course you could cache it in master and let client go to master to ask for the state. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
