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?
