FlinkパッケージがありませんクラスCheckpointCommitter - flink-connector-cassandra - ハードエラー

Question

私のローカル環境でFlink（v 1.0.3）に新しいジョブを送信するときにこのエラーが発生します。

によって引き起こさ：java.lang.NoClassDefFoundErrorが：ORG/apacheの/ FLINK /ストリーミング/ランタイム/オペレーターorg.apache.flink.streaming.connectors.cassandra.CassandraSink.addSinkで/ CheckpointCommitter （CassandraSink.java:164） sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.javaでsun.reflect.NativeMethodAccessorImpl.invoke0（ネイティブメソッド） でcom.xxx.yyy.sample.backend.flink.AAAAA.main（AAAAA.java:99） で：62） at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43） at java.lang.reflect.Method.invoke（Method.java：498） at org.apache.flink.client.program.PackagedProgram .callMainMethod（PackagedProgram.java:505） at org.apache.flink.client.program.PackagedProgram.invokeInteractiveModeForExecution（PackagedProgram.java:403） at org.apache.flink.client.program.OptimizerPlanEnvironment.getOptimizedPlan（OptimizerPlanEnvironment.java:80） ... 33もっと見るgithubのソースコード

https://github.com/apache/flink/tree/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/operators

を見てみると 私はクラスが利用可能であるべき、それはFLINKストリーミング-java.jarにパッケージされるべきであると思うだろうが、ファイルがインポートされると、このクラスではありませんそこに

missing CheckpointCommitter

アイデア？

Answer 1

私が持っていました同様の問題。私のために修正されたのは、ソースで使用されているKafkaConsumer/Producerが、あなたが依存しているものと一致していることを確認することでした。FlinkKafkaCの異なるバージョン間で競合が発生しているようですオンサマー。

（あなたがプロデューサーを使用している場合、またはプロデューサ）あなたはFlinkKafkaConsumer08を使用してのではなくFlinkKafkaConsumerされていることを確認し

<dependency> 
    <groupId>org.apache.flink</groupId> 
    <artifactId>flink-connector-kafka-0.8_2.10</artifactId> 
    <version>1.0.2</version> 
</dependency> 

このインポートを使用して

私にとっては奇妙なことは、私のIDEは解決できないということですFlinkKafkaConsumer08が、ビルドツールを使用してコンパイルされ、正しく実行されます。
