>                 URL: https://issues.apache.org/jira/browse/TEZ-2270
>             Project: Apache Tez
>          Issue Type: Bug
>    Affects Versions: 0.7.0
>            Reporter: Gopal V
>
> When a Tez AM is started with a LocalResource which is also present on the cluster, the added JAR should be preferred to the cluster version (during rolling upgrades).
> Running a different version on an existing cluster results shows incompatibilities triggered by the fact that the tez.tar.gz files are ahead of the cluster classpath, while the LocalResources are added after the cluster classpath.
> Mixing the order up results in the user-added JAR being ineffective in forcing the client version over the cluster version.
