Still works fine for me even with clearing the local artifact and cleaning.
I have the exact same Maven from brew.
```
rm -fr ~/.m2/repository/org/eclipse/paho/
mvn -U -Pyarn -Dhadoop.version=2.2.0 -Dyarn.version=2.2.0 -DskipTests clean
compile
```
I show that it is downloading from the eclipse repo:
```
Downloading:
https://repo.eclipse.org/content/repositories/paho-releases/org/eclipse/paho/mqtt-client/0.4.0/mqtt-client-0.4.0.pom
Downloaded:

```
That's to be expected since this repo is configured in the `external/mqtt`
module. I see code usages in this module, and in examples (where you see the
failure), but the example module does depend on the MQTT module.
Try the `install` goal instead? maybe it's not finding your copy of the
snapshot build locally.
