MongoDB Connector for Hadoop has been certified on top three Hadoop vendors including MapR, Hortonworks, and Cloudera. The connector allows customers to use MongoDB as an input source and/or output destination for Hadoop deployments, making it a perfect technology complement to Hadoop. Companies like Orbitz and the City of Chicago are using MongoDB and Hadoop together to deliver real-time pricing and predictive analytics platforms, respectively. Additionally, MongoDB can be used in combination with Hadoop for various use cases such as ecommerce, insurance, and more, by storing data, running real-time recommendations, detecting fraud, conducting customer action analysis, and creating churn prediction algorithms.
