jnioche opened a new issue #2890: Dependencies for using Pulsar in Storm topologies
URL: https://github.com/apache/pulsar/issues/2890
**Pulsar version**: 2.2.0
I build an uber jar for a Storm toplogy containing the following dependency as per http://pulsar.apache.org/docs/latest/adaptors/PulsarStorm/
```
<properties>
<pulsar.version>2.2.0</pulsar.version>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.pulsar</groupId>
<artifactId>pulsar-storm</artifactId>
<version>${pulsar.version}</version>
</dependency>
</dependencies>
```
am getting
```

```
so I added the following dependency explicitly
```
<dependency>
<groupId>org.asynchttpclient</groupId>
<artifactId>async-http-client</artifactId>
<version>2.1.0-alpha26</version>
</dependency>
```
which seems to solve this particular problem. Shouldn't the documentation list that dependency?
Am then getting an endless stream of errors in the logs
```

```
I checked the dependencies and that class and method seem to be there. Any idea?
See https://github.com/DigitalPebble/storm-crawler/tree/pulsar/external/pulsar for the code I wrote based on your Storm adaptor. Thanks!
