Launch your upgraded Heron topology</h2> |
| <p>You can launch the compiled Maven project on your <a href="schedulers-local">local |
| cluster</a> using <code>heron submit</code>.</p> |
| <p>First, modify your project's base directory <code>{basedir}</code> and |
| <code>{PATH-TO-PROJECT}.jar</code>, which is located in <code>${basedir}/target</code> by <a href="https://maven.apache.org/guides/getting-started/">Maven |
| convention</a>. Then modify the |
| <code>TOPOLOGY-FILE-NAME</code> and <code>TOPOLOGY-CLASS-NAME</code> for your project:</p> |
| <pre><code class="hljs css language-bash">$ heron submit <span class="hljs-built_in">local</span> \ |
| <span class="hljs-variable">${basedir}</span>/target/PATH-TO-PROJECT.jar \ |
| TOPOLOGY-FILE-NAME \ |
| TOPOLOGY-CLASS-NAME |
| </code></pre> |
| <p>Here's an example submit command using the example topology from the <a href="getting-started-local-single-node">Quick |
| Start Guide</a> guide:</p> |
| <pre><code class="hljs css language-bash">$ heron submit <span class="hljs-built_in">local</span> \ |
| ~/.heron/examples/heron-api-examples.jar \ <span class="hljs-comment"># The path of the topology's jar file</span> |
| org.apache.heron.examples.api.ExclamationTopology \ <span class="hljs-comment"># The topology's Java class</span> |
| ExclamationTopology <span class="hljs-comment"># The name of the topology</span> |
