Namenode cluster(multi namenode working in active-active mode) to keep high availability and
expansivity
--------------------------------------------------------------------------------------------------------

                 Key: HADOOP-3596
                 URL: https://issues.apache.org/jira/browse/HADOOP-3596
             Project: Hadoop Core
          Issue Type: New Feature
          Components: dfs
         Environment: Hadoop cluster on more than thousands of nodes, most of all, the number
of files is mass.
            Reporter: Meng Xu


 If we use the DFS to store a great quantity of files which is very small, i.e. the namenode
is under high pressure of indexing files, should we consider to introduce other namenodes
working concurrently for availability and scalability?
