Hedera
Hedera is a framework to facilitate the rapid development of processing methods on big versioned document collections using the Hadoop framework. It provides customized InputFormat for accessing data in parallel in standard MapReduce workflows. It also has new mechanism of extracting and transforming while loading (versus the traditional Extraction, Transformation, Loading or ETL) to reduce the IO burden when passing large amounts of data through a cluster. Hedera can be used in Hadoop Streaming to enable rapid development using different languages (Java, Python, C, etc.) , and it also supports Pig with a number of User-defined functions (UDFs). At the moment, the framework has been tested in Hadoop CDH 4.x and Pig 0.11.x. It supports both Hadoop YARN and non-YARN models.
