Subject [jira] [Resolved] (TEZ-3553) NoClassDefFoundError in TexConfiguration
Date Thu, 01 Dec 2016 15:56:58 GMT

     [ https://issues.apache.org/jira/browse/TEZ-3553?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hitesh Shah resolved TEZ-3553.
------------------------------
    Resolution: Invalid

Please take a look at http://tez.apache.org/install.html. 

Instead of adding each sub-dir of tez-src into the classpath, I would suggest compiling tez
and then using the tarballs created in tez-dist/target to update the classpath. 

For usage questions such as this, it is better to ask on the user mailing list. If the mailing
list discussion results into a bug being discovered, then a bug should be filed.

> 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.
