Looking to Stay Ahead of Hortonworks and MapR in the Hadoop Market, Cloudera Delivers High Availability, Better Security, and Easier System Management
Compare the title, which is the subtitle of the InformationWeek post, with this paragraph which reflects the reality:
Both Cloudera and Hortonworks will be distributing open source software from Apache’s Hadoop 2.3 release, which includes upgrades aimed at high-availability and improved security. The release includes a hot-failover for the NameNode (metadata server) of the Hadoop Distributed File System (HDFS), which has long been a single point of failure.
Cloudera is indeed one of the biggest Hadoop contributors and a company that have helped a lot proving and thus popularizing Hadoop through their packaging of open source Hadoop ecosystem components paired with their management tool (Cloudera Manager). But NameNode high availability and security improvements are part of the Apache Hadoop source code.
