[jira] [Commented] (TEZ-4074) Tez does not run with Hadoop Trunk (3.3.0-snapshot)

["Ahmed Hussein (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TEZ-4074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16853032#comment-16853032 ] 

Ahmed Hussein commented on TEZ-4074:
------------------------------------

Guava27 and 11.0.2 are not source compatible.

For example, Guava27 removed API methods such as {{Futures.addCallback(ListenableFuture<V> future, FutureCallback<? super V> callback)}}
 * Guava11.0.2: [FutureCallback|https://google.github.io/guava/releases/11.0.2/api/docs/com/google/common/util/concurrent/Futures.html#addCallback(com.google.common.util.concurrent.ListenableFuture,%20com.google.common.util.concurrent.FutureCallback)]
 * Guava27: [FutureCallback|https://static.javadoc.io/com.google.guava/guava/27.0.1-jre/com/google/common/util/concurrent/Futures.html#addCallback-com.google.common.util.concurrent.ListenableFuture-com.google.common.util.concurrent.FutureCallback-java.util.concurrent.Executor-]

> 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.
