----------------------------------

             Summary: Tez does not run with Hadoop Trunk (3.3.0-snapshot)
                 Key: TEZ-4074
                 URL: https://issues.apache.org/jira/browse/TEZ-4074
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Ahmed Hussein


Tez throws a runtime exception when compiled against Hadoop-3.3.0.

With Tez running Guava (11.0.2) and Hadoop eunning Guava 27.0-jre (see HADOOP-16210), there is an incompatibility of Guava library.

{code}
It looks like guava added single parameter optimizations which breaks compatibility with {{VAR_ARGS}}. So, even though it shows source compatibility it is throwing a runtime error due to binary incompatibility.
