Description

We deploy Tez 0.8.4 on Hadoop 2.7.2. Now we do not use Yarn in our work and do a test about Tez. The installation of Tez is successful and report no error. However, when I run the tex-example.jar, we find a fatal error that the TexConfiguration cannot be found.

The error report is here
```

   The `hadoop_classpath` is

The tez configure file is
```
