Hi, all, I am NOT sure if there any plan or issues of integrating Zookeeper and NameNode to resolve the Single Point issue of NameNode. With it, the DataNodes dont need to be restarted. I think this can improve the availability of the whole cluster. I heard there is a plan for JobTracker and TaskTracker, but i dont know if there is the one for HDFS. Currently, i am working on it. :)
Any issues or comments are welcome. regards macf
