+
+How to use Python components in an Apache Storm topology on HDInsight
+
+This topology uses the Flux framework to define a Storm topology using YAML. The components (spout and bolts) that process the data are written in Python.
+
+This example has been tested with HDInsight 3.6 (Storm 1.1.0).
+
+## Prerequisites
+
+* Python 2.7 or higher
+
+* Java JDK 1.8 or higher
+
+* Maven
+
+* (Optional) A local Storm development environment. This is only needed if you want to run the topology locally. For more information, see [Setting up a development environment](http://storm.apache.org/releases/1.0.1/Setting-up-development-environment.html).
+
+## How it works
+
+* `/resources/topology.yaml` - defines what components are in the topology and how data flows between them.
+
+* `/multilang/resources` - contains the Python components.
+
+* `/pom.xml` - dependencies and how to build the project.
+
+## Build the project
+
+From the root of the project, use the following command:
+
+```bash
+mvn clean compile package
+```
+
+This command creates a `target/WordCount-1.0-SNAPSHOT.jar` file.
+
+## Run the topology locally
+
+To run the topology locally, use the following command:
+
+```bash
+storm jar WordCount-1.0-SNAPSHOT.jar org.apache.storm.flux.Flux -l -R /topology.yaml
+```
+
+Once the topology starts, it emits information to the local console similar to the following text:
+
+```
+24302 [Thread-25-sentence-spout-executor[4 4]] INFO o.a.s.s.ShellSpout - ShellLog pid:2436, name:sentence-spout Emiting the cow jumped over the moon

+24303 [Thread-17-log-executor[3 3]] INFO o.a.s.f.w.b.LogInfoBolt - {word=seven, count=302}
+24303 [Thread-17-log-executor[3 3]] INFO o.a.s.f.w.b.LogInfoBolt - {word=dwarfs, count=143}
+24303 [Thread-25-sentence-spout-executor[4 4]] INFO o.a.s.s.ShellSpout - ShellLog pid:2436, name:sentence-spout Emiting the cow jumped over the moon
+24303 [Thread-30] INFO o.a.s.t.ShellBolt - ShellLog pid:2438, name:splitter-bolt Emitting cow
+^C24303 [Thread-17-log-executor[3 3]] INFO o.a.s.f.w.b.LogInfoBolt - {word=four, count=160}
+```
+
+Use Ctrl+c to stop the topology.
+
+## Run the topology on HDInsight
+
+1. Use the following command to copy the `WordCount-1.0-SNAPSHOT.jar` file to your Storm on HDInsight cluster:
+
+ ```bash
+ scp target\WordCount-1.0-SNAPSHOT.jar sshuser@mycluster-ssh.azurehdinsight.net
+ ```
+
+ Replace `sshuser` with the SSH user for your cluster. Replace `mycluster` with the cluster name.
+
+2. Once the file has been uploaded, connect to the cluster using SSH and use the following command to start the topology on the cluster:
+
+ ```bash
+ storm jar WordCount-1.0-SNAPSHOT.jar org.apache.storm.flux.Flux -r -R /topology.yaml
+ ```
+
+3. You can use the Storm UI to view the topology on the cluster. The Storm UI is located at https://mycluster.azurehdinsight.net/stormui. Replace `mycluster` with your cluster name.
+
+Once started, a Storm topology runs until stopped (killed.) To stop the topology, use either the `storm kill TOPOLOGYNAME` command from the command-line (SSH session to a Linux cluster,) or by using the Storm UI, select the topology, and then select the __Kill__ button.
