WANdisco Launches Non-Stop NameNode for 100% Hadoop Uptime

WANdisco Applies Patented Non-Stop Technology to Meet Hadoop Availability, Performance and Scalability Requirements

SANTA CLARA, CA -- (Marketwire) -- 02/27/13 -- Strata -- WANdisco (LSE: WAND), a provider of high-availability software for global enterprises to meet the challenges of Big Data and distributed software development, today announced the availability of its Non-Stop NameNode, the only 100 percent uptime solution for Hadoop. Non-Stop NameNode completely eliminates the single point of failure that risks data availability -- the NameNode -- which tracks the data's location within a Hadoop cluster and coordinates client access to it.

"This announcement demonstrates our commitment to enterprises looking to deploy Hadoop in their production environments today," said David Richards. "If the NameNode is unavailable, the Hadoop cluster goes down. With other solutions, a single NameNode server actively supports client requests and complex procedures are required if a failure occurs. The Non-Stop NameNode eliminates those issues and also allows for planned maintenance without downtime. WANdisco provides 100% uptime with unmatched scalability and performance."

Built on the company's Non-Stop patented technology for deployment on Apache Hadoop 2, its own distribution, WANdisco Distro, or Cloudera's CDH, Non-Stop NameNode enables multiple active NameNode servers to act as peers, maintaining continuous synchronization and simultaneously supporting client access to the Hadoop cluster. If one server fails, or is taken down for scheduled maintenance, others take over automatically without any downtime. When the server comes back up, it immediately resynchronizes itself with the others in the cluster and resumes normal operation. This completely eliminates the risk of downtime and data loss due to human error during failover and recovery.

"Hadoop was not originally developed to support real-time, mission critical applications, and thus its inherent single point of failure was not a major issue of concern," said Jeff Kelly, Big Data Analyst at Wikibon. "But as Hadoop gains mainstream adoption, traditional enterprises rightly are looking to Hadoop to support both batch analytics and mission critical apps. With WANdisco's unique Non-Stop NameNode approach, enterprises can feel confident that mission critical applications running on Hadoop, and specifically HBase, are not at risk of data loss due to a NameNode failure because, in fact, there is no single NameNode. This is a major step forward for Hadoop."

"WANdisco is delivering Hadoop solutions for enterprises with mission critical applications," said Mani Chhabra, CEO of Cloudwick Technologies, a provider of professional Big Data services and WANdisco systems integration partner. "Non-Stop NameNode removes the single point of failure risk, which eliminates the challenge enterprises currently face with Hadoop. WANdisco is the first company delivering solutions capable of deploying global Hadoop clusters spanning multiple data centers. We're excited to be one of their first Big Data partners."

Following are some key features of the Non-Stop NameNode:

  • Every server is a continuous hot backup of every other. This is leveraged to provide automated failover and recovery after server outages without administrator intervention.
  • Non-Stop NameNode automated failover and recovery features can be used to eliminate downtime for scheduled maintenance.
  • Risk of data corruption due to "split-brain" is eliminated because all NameNode servers actively support clients and are always in sync.
  • Non-Stop NameNode scales as more servers are added to the cluster to support increased workload without sacrificing performance
  • Unlike other solutions limited to a LAN or Metropolitan Area Network, WANdisco's Non-Stop NameNode delivers the same capabilities over a WAN regardless of distance, enabling global business continuity
  • Provides full support for HBase and works with Hadoop 2, WANdisco Distro (WDD) and CDH 4.1.x
