    • Hadoop cluster on more than thousands of nodes, most of all, the number of files is mass.

    Description

      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?
