---------------------------------
Summary: NoClassDefFoundError in TexConfiguration
Key: TEZ-3553
URL: https://issues.apache.org/jira/browse/TEZ-3553
Project: Apache Tez
Issue Type: Bug
Affects Versions: 0.8.4
Environment: Ubuntu. Hadoop 2.7.2. Tez 0.8.4.
Reporter: Shengjie Luo
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
```
