Built on WANdisco's patented replication technology, the Non-Stop NameNode is the first and only 100% uptime solution for Hadoop that eliminates the most problematic single point of failure impacting availability — the NameNode — which tracks the location of data within a Hadoop cluster and coordinates client access to it.
The Non-Stop NameNode enables multiple active NameNode servers to act as peers, continuously synchronized and simultaneously supporting client access for batch applications using MapReduce, as well as real-time applications using HBase. When one NameNode server fails, others take over automatically without any downtime. These capabilities enable the Non-Stop NameNode to deliver 100% uptime with unmatched scalability and performance.Free Trial
