Su Ralph commented on FLINK-6126:
---------------------------------
This looks due to incorrect local build of flink.
Documentation at
https://ci.apache.org/projects/flink/flink-docs-release-1.2/setup/building.html
shows clearly that
"""
NOTE: Maven 3.3.x can build Flink, but will not properly shade away certain
dependencies. Maven 3.0.3 creates the libraries properly. To build unit tests
with Java 8, use Java 8u51 or above to prevent failures in unit tests that use
the PowerMock runner.
"""
My local flink jar was build by maven3.3.3, which the shade of guava is not
well set. Cause the conflict of elastic search(guava 18) and the packaged
ones(should be the ones from hadoop related).
> Yet another conflict : guava

> When write a user function try to write to elastic search (depend on
> elasticsearch 2.3.5)
> Stack like:
> java.lang.NoSuchMethodError:
> com.google.common.util.concurrent.MoreExecutors.directExecutor()Ljava/util/concurrent/Executor;
> at
> org.elasticsearch.threadpool.ThreadPool.<clinit>(ThreadPool.java:190)
> at
> org.elasticsearch.client.transport.TransportClient$Builder.build(TransportClient.java:131)
> at
> io.sherlock.capabilities.es.AbstractEsSink.open(AbstractEsSink.java:98)
> When enable env.java.opts.taskmanager to -version:class, we can see the class
> load log like:
> [Loaded com.google.common.util.concurrent.MoreExecutors from
> file:/opt/flink/lib/flink-dist_2.11-1.2.0.jar]
