California-based enterprise software company Cloudera has launched the fourth generation of its Apache Hadoop data management platform, Cloudera Enterprise 4.0.
Cloudera Enterprise 4.0 Big Data platform combines the company’s Cloudera Manager software with technical support to deliver a turnkey system for deploying and managing Hadoop in production as well as use, integrate and adopt Apache Hadoop.
The company has also released CDH4 (Cloudera’s Distribution Including Apache Hadoop, version 4), an open source application that combines Apache Hadoop with other open source applications within the Hadoop stack to deliver advanced, enterprise-grade features.
Cloudera Enterprise 4.0 and CDH4 are combined to form an end-to-end application that enables enterprises to integrate Hadoop with their existing enterprise data management systems for mission-critical applications.
The combined application is expected to deliver new features that support higher availability, increased security, improved extensibility and improved automation for management of large scale Hadoop clusters.
CDH4 offers increased usability for mission critical use cases and applications with a NameNode that eliminates the remaining single point of failure in HDFS. Heterogeneous clusters minimises downtime and allows users to run different nodes on different versions of Hadoop.
It will also allow sensitive data to be stored in CDH with granular access control to support multi-tenancy and will solve several scenarios through coprocessors that enable real time and open resource management that allows for multiple data processing frameworks to run on the same Hadoop cluster.
Cloudera Manager 4, the new version of the management component of Cloudera Enterprise, includes a 3-Step HA Configuration that guides setup for the NameNode in three simple steps: Multi-Cluster Management allows for management of multiple clusters from a single instance of Cloudera Manager, and Backwards Compatibility offers flexibility in management with support for both CDH3 and CDH4.
Manager 4 includes heat maps to administrators to identify problem nodes within large clusters and take action. It also includes the federated NameNode management, which simplifies the process of growing CDH clusters to billions of files across thousands of nodes.
The Cloudera Manager API integrates with existing enterprise management and monitoring tools. Cloudera Manager also includes support for LDAP authentication and now supports additional databases, including Oracle and PostgreSQL and includes new packages for Ubuntu and Debian.
