As a replacement execution engine for Hadoop-style MapReduce jobs, ScaleOut hServer was designed with Java API support. Our C++ NamedCache APIs are designed to be used with our ScaleOut StateServer product. Our hServer samples are located in the product installation directory underneath the samples sub-directory.
ScaleOut hServer was designed to enable Apache Hadoop MapReduce jobs to run unchanged using our in-memory execution engine and optionally access “live” datasets hosted within our distributed, in-memory data grid. We have not explored providing APIs for Clojure since our focus is on compatibility with Hadoop MapReduce.
