| Apache REEF™ |
| ======================== |
| |
| Apache REEF™ (Retainable Evaluator Execution Framework) is a library for developing portable applications for |
| cluster resource managers such as Apache Hadoop YARN or Apache |
| Mesos. For example, [Microsoft Azure Stream Analytics](https://azure.microsoft.com/en-us/services/stream-analytics/) is built on [REEF and |
| Hadoop.](https://blogs.technet.microsoft.com/machinelearning/2015/12/17/reef-graduates-to-a-top-level-apache-project/) |
