# HelloREEF This project contains a simple example of a REEF Program. It contains the following classes:
HelloREEF
: This is the program that submits the driver to the local runtime.HelloDriver
: The Driver requests a single Evaluator and submits the HelloTask
to it.HelloTask
: This Task prints a greeting to STDOUT of the Evaluator.Just run the main class, HelloREEF
, followed by the runtime you want, e.g. local
.
To use HelloREEF as a standalone application, the only changes necessary are installing dependencies and adding a build step to the .csproj file.

References
to the .csproj file<Reference Include="Org.Apache.REEF.Evaluator, Version=0.16.0.0, Culture=neutral, PublicKeyToken=c27bf5b2e9a7ddb9, processorArchitecture=AMD64\"> <HintPath>packages/Org.Apache.REEF.Evaluator.0.16.0/tools/Org.Apache.REEF.Evaluator.exe</HintPath> </Reference>
Now HelloREEF can be used as the first step of writing a new application with Apache REEF.
