| # 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. |
| |
| ## Running it |
| Just run the main class, `HelloREEF`, followed by the runtime you want, e.g. `local`. |
| |
| ## Using as a Standalone Application |
| To use HelloREEF as a standalone application, the only changes necessary are installing dependencies and adding a build step to the .csproj file. |
| |
| Directions |
| 1. Copy all the \*.cs files to a new directory |
| 2. In Visual Studio, create a new project from these files |
| 3. Change the namespaces to `HelloREEF` |
| 4. Change the .NET framework to `4.5.1` |
| 5. Change the target platform to `x64` |
| 6. Use the NuGet to install all dependencies necessary to build the project |
| 7. Add the following `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> |
| ``` |
| 8. Build the project one last time |
| |
| Now HelloREEF can be used as the first step of writing a new application with Apache REEF. |
