Overview of Cloudera and the Cloudera Documentation Set
Cloudera provides a scalable, flexible, integrated platform that makes it easy to manage rapidly increasing volumes and varieties of data in your enterprise. Cloudera products and solutions enable you to deploy and manage Apache Hadoop and related projects, manipulate and analyze your data, and keep that data secure and protected.
- CDH—The Cloudera distribution of Apache Hadoop and other related open-source projects,
including Impala and Cloudera Search. CDH also provides security and integration with numerous hardware and software solutions.
- Cloudera Impala—A massively parallel processing SQL engine for interactive analytics and business intelligence. Its highly optimized architecture makes it ideally suited for traditional BI-style queries with joins, aggregations, and subqueries. It can query Hadoop data files from a variety of sources, including those produced by MapReduce jobs or loaded into Hive tables. The YARN resource management component lets Impala coexist on clusters running batch workloads concurrently with Impala SQL queries. You can manage Impala alongside other Hadoop components through the Cloudera Manager user interface, and secure its data through the Sentry authorization framework.
- Cloudera Search—Provides near real-time access to data stored in or ingested into Hadoop and HBase. Search provides near real-time indexing, batch indexing, full-text exploration and navigated drill-down, as well as a simple, full-text interface that requires no SQL or programming skills. Fully integrated in the data-processing platform, Search uses the flexible, scalable, and robust storage system included with CDH. This eliminates the need to move large data sets across infrastructures to perform business tasks.
- Cloudera Manager—A sophisticated application used to deploy, manage, monitor, and diagnose issues with your CDH deployments. Cloudera Manager provides the Admin Console, a web-based user interface that makes administration of your enterprise data simple and straightforward. It also includes the Cloudera Manager API, which you can use to obtain cluster health information and metrics, as well as configure Cloudera Manager.
- Cloudera Navigator—An end-to-end data management and security tool for the CDH platform. Cloudera Navigator enables administrators, data managers, and analysts to explore the large amounts of data in Hadoop, and simplifies the storage and management of encryption keys. The robust auditing, data management, lineage management, lifecycle management, and encryption key management in Cloudera Navigator allow enterprises to adhere to stringent compliance and regulatory requirements.
