classpath issue on yarn
Hi guys,I ran into a weird classpath issue while running a streaming job on a yarn cluster.I have a relatively simple flow that reads data from kafka, does a few manipulations and then indexes them on Elasticsearch (2.3).I use the elasticsearch2 connector (1.1-SNAPSHOT) (bleeding edge, I know).The stream works fine in a local flink node (1.0.2) (reading from remote kafka and writing to remote es).However, when deployed to the remote YARN cluster (again, flink 1.0.2) the following exception is thrown:```04/26/2016 10:07:30 Source: Custom Source -> Flat Map -> Sink: Unnamed(1/8) switched to FAILED 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$Builder.build(TransportClient.java:131) at org.apache.flink.streaming.connectors.elasticsearch2.ElasticsearchSink.open(ElasticsearchSink.java:164) at org.apache.flink.api.common.functions.util.FunctionUtils.openFunction(FunctionUtils.java:38) at org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator.open(AbstractUdfStreamOperator.java:91) at org.apache.flink.streaming.runtime.tasks.StreamTask.openAllOperators(StreamTask.java:317) at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:215) at org.apache.flink.runtime.taskmanager.Task.run(Task.java:559) at java.lang.Thread.run(Thread.java:745)04/26/2016 10:07:30 Job execution switched to status FAILING.java.lang.NoSuchMethodError: com.google.common.util.concurrent.MoreExecutors.directExecutor()Ljava/util/concurrent/Executor; at org.elasticsearch.threadpool.ThreadPool.<clinit>(ThreadPool.java:190) at org.elasticsearch.client.transport.TransportClient$Builder.build(TransportClient.java:131) at org.apache.flink.streaming.connectors.elasticsearch2.ElasticsearchSink.open(ElasticsearchSink.java:164) at org.apache.flink.api.common.functions.util.FunctionUtils.openFunction(FunctionUtils.java:38) at org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator.open(AbstractUdfStreamOperator.java:91) at org.apache.flink.streaming.runtime.tasks.StreamTask.openAllOperators(StreamTask.java:317) at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:215) at org.apache.flink.runtime.taskmanager.Task.run(Task.java:559) at java.lang.Thread.run(Thread.java:745)04/26/2016 10:07:30 Source: Custom Source -> Flat Map -> Sink: Unnamed(7/8) switched to FAILED java.lang.NoClassDefFoundError: Could not initialize class org.elasticsearch.threadpool.ThreadPool at org.elasticsearch.client.transport.TransportClient$Builder.build(TransportClient.java:131) at org.apache.flink.streaming.connectors.elasticsearch2.ElasticsearchSink.open(ElasticsearchSink.java:164) at org.apache.flink.api.common.functions.util.FunctionUtils.openFunction(FunctionUtils.java:38) at org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator.open(AbstractUdfStreamOperator.java:91) at org.apache.flink.streaming.runtime.tasks.StreamTask.openAllOperators(StreamTask.java:317) at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:215) at org.apache.flink.runtime.taskmanager.Task.run(Task.java:559) at java.lang.Thread.run(Thread.java:745)```I rebuilt the fat jar (I use sbt) many times and in my fat jar there is no trace of the old guava `MoreExecutor` class that doesn't contain the `directExecutor` method the transport client needs.`lib/flink-dist_2.11-1.0.2.jar` unfortunately contains both: the newest class coming from guava 18 and an old one introduced probably by some ancient hadoop dependency.

So,I shaded guava.The whole think works fine locally (stand alone local flink), but on yarn (forgot to mention it runs on EMR), I get the following:org.apache.flink.client.program.ProgramInvocationException: Unknown I/O error while extracting contained jar files. at org.apache.flink.client.program.PackagedProgram.extractContainedLibaries(PackagedProgram.java:729) at org.apache.flink.client.program.PackagedProgram.<init>(PackagedProgram.java:192) at org.apache.flink.client.CliFrontend.buildProgram(CliFrontend.java:922) at org.apache.flink.client.CliFrontend.run(CliFrontend.java:301) at org.apache.flink.client.CliFrontend.parseParameters(CliFrontend.java:1192) at org.apache.flink.client.CliFrontend.main(CliFrontend.java:1243)Caused by: java.util.zip.ZipException: error in opening zip file at java.util.zip.ZipFile.open(Native Method) at java.util.zip.ZipFile.<init>(ZipFile.java:219) at java.util.zip.ZipFile.<init>(ZipFile.java:149) at java.util.jar.JarFile.<init>(JarFile.java:166) at java.util.jar.JarFile.<init>(JarFile.java:130) at org.apache.flink.client.program.PackagedProgram.extractContainedLibaries(PackagedProgram.java:647) ... 5 moreI removed the shaded dependency and I got back to the previous error.Any clues?Thanks,Aris

Hi Robert,
Thank you for your prompt response.No, I downloaded it from an apache mirror.I think yarn loads the hadoop universe before the user classpath by default, so I reckon I would get this exception even without flink in the middle.I can still see both the old and the new MoreExecutors class in flink-dist (the old as org/apache/flink/hadoop/shaded/com/google/common/util/concurrentthe new as org/apache/flink/shaded/com/google/common/util/concurrent)I reckon I should try to shade guava in my side, but the Shade plugin in sbt-assembly is quite fresh.
I will try and report.
Thanks,Aris

Hi Aris,
Did you build the 1.0.2 flink-dist yourself?If not, which exact version did you download?For example this file: http://www.apache.org/dyn/closer.lua/flink/flink-1.0.2/flink-1.0.2-bin-hadoop2-scala_2.11.tgz has a clean flink-dist jar.
