Non-Stop NameNode


Non-Stop NameNode


Non-Stop NameNode WAN Edition

Non-Stop NameNode WAN Edition applies WANdisco’s patented replication technology to deliver 100% uptime by eliminating Hadoop’s most problematic single point of failure — the NameNode — providing the first and only continuous availability solution for globally distributed deployments. With it, all NameNode servers in a Hadoop cluster deployed over a WAN actively support clients at each location and along with the data nodes, are continuously synchronized. The result is LAN-speed performance and access to the same data at every location. Failover and recovery are automatic both within and across data centers. Whether a single NameNode or an entire site goes down, Hadoop is always available.


Non-Stop NameNode LAN Edition

Non-Stop NameNode LAN Edition applies WANdisco’s patented replication technology to deliver 100% uptime by eliminating Hadoop’s most problematic single point of failure — the NameNode — providing the first and only continuous availability solution for deployments over a local area network. Non-Stop NameNode LAN Edition enables multiple active NameNode servers to act as peers, continuously synchronized and simultaneously supporting client access for unparallelled performance and scalability. When a NameNode fails or is taken offline for maintenance, other active NameNodes continue supporting clients without any interruption in access.
